What is a JB4?

The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade and is sold in over 67 countries worldwide.

Is the JB4 a real tune?

Yes the JB4 is a real tune. By tapping into specific sensors and CANbus for real time vehicle data the JB4 is able to alter your boost, timing, AFR, and/or fuel trims, to a similar degree an ECU reflash would, but without the vehicle ever knowing its been tuned. The result is safe, smooth, and significant power and torque gains while retaining your factory safety systems and without having to unlock/flag your ECU.

The first shall be last, literally, here
Format: Hardcover, Format: Hardcover
It's funny that this is the last book to complete the set, but it's also the first volume. This Pentateuch set offers a great commentary set for those looking for something more than a study Bible, but something less than a full, highly technical, original language, word-by-word study. This review will be a higher-level one rather than a review per volume. Each book of the Bible has its own author, but the layout is the same, with an overview of the book, a section outline, then a section with commentary. The typeface of this is perfect. It's big enough to be easily read and spaced out to not get lost per line. The footnotes are exactly where they need to be, at the bottom of the page but not so overencumbered that you get lost in the footnotes rather than in the main text. The books from page 1 to the last page sit open perfectly without ruining the binding or spine. There's no need to grab two other commentaries just to read and take notes from. That's impressive for these volumes in and of themselves! The division for each combination of books makes sense and also helps if you're studying genre (like 1 & 2 Timothy with Titus, or the Pentateuch). Editors Iain M. Duguid, James M. Hamilton Jr., and Jay Sklar sometimes take over a commentary section but they've picked from some good authors. Their purpose of what they're looking for in the authors are stated in each book. Being broadly Reformed and conservative while being globally minded and not overly exhaustive again points to the well-ordered nature of this set. The Hebrew is transliterated, which again points to this set being inclusive to a wider audience to approach it while still being helpful and a great source of teaching. For the price point, I think purchasing this is useful, especially as a family used commentary set from teens on up.

Review of Crossway’s ESV Expository Commentary: Genesis–Numbers The Final Volume in a Landmark 12-Book Set Crossway’s release of the ESV Expository Commentary: Genesis–Numbers marks the long-awaited completion of their 12-volume expository commentary set ,a project that has served pastors, teachers, and lay readers with a rare blend of theological depth and pastoral warmth. This final installment offers rich insight into the foundational books of Scripture, bringing the story of God's redemptive plan into sharp focus right from the beginning. Theological Clarity Meets Pastoral Sensitivity Covering Genesis through Numbers, this volume tackles some of the Bible's most theologically significant and narratively complex material including creation, covenant, the patriarchs, the Exodus, and the wilderness wanderings. The contributors succeed in making ancient texts accessible, relevant, and worshipful without sacrificing exegetical rigor. Each passage is explained in context, showing how the Law and the beginnings of Israel's story point forward to Christ. Format and Usefulness True to the style of the series, this commentary is structured passage-by-passage, making it perfect for sermon preparation, Bible teaching, or devotional study. The tone is neither academic nor overly simplified—it’s pastoral, clear, and rooted in the authority of Scripture. The layout also includes helpful section summaries, theological insights, and practical application points. As always, all Scripture quotations are from the ESV, helping readers stay immersed in one translation. Series Finale Done Right As the first volume in biblical order but the last in publication, Genesis–Numbers fittingly brings the entire ESV Expository Commentary project full circle. It is a fitting capstone to a series that has been praised for its faithful interpretation, readability, and usefulness across denominations. Whether you're just beginning to explore the Bible or you're a seasoned preacher, this commentary and the series as a whole offers a trustworthy companion for growing deeper in God’s Word. Crossway has given the church a gift that will serve this generation and the next.

Nicely made and easy to read
Format: Hardcover
This arrived well packaged, but despite this, the two top corners of the book were somewhat smashed and there was more significant damage at the bottom of the spine where it was smashed. There is also some damage on the spine itself at about the level where Crossway is printed. The book appears well made and the paper is a good quality and thick. The print is of a nice size. One will most likely never access all the information enclosed in this commentary. In addition, one will most likely not agree with everything written, which should be expected of all commentaries. Commentaries are simply that and not authoritative. One hopes that by reading they might learn something new or be prompted to look more closely at a subject or issue. Let's look at Leviticus 11, for example, where the dietary guidelines are given to the Israelites. In the comments regarding pigs being forbidden, it is noted that the Philistines raised pigs for food. Knowing that, one can come to a conclusion that this may be why they were forbidden, so as to make a difference, or distinction, between the two peoples and not necessarily that pigs were bad to eat. In addition, throughout the commentary the reader is taken not just to other Old Testament passages, but where applicable the New Testament is referenced. Again using Leviticus 11, at the end of the chapter the commentary brings up the Jerusalem Council in Acts 15 when they issued the four requirements for Gentiles. It is noted that, "The Jerusalem Council agreed on four nonnegotiables to bring Jewish and Gentile believers to the same table, drawn in large measure from Leviticus's laws on holy living for the resident alien."

The Final Volume of An Excellent Commentary Series Does Not Disappoint
Format: Hardcover
After 7 years, Crossway has completed their ESV Expository Commentary set. Ironically, Vol. 1, was the last of the twelve volumes to be completed. It fully lives up to the standard the other eleven set. Like the other volumes, it focuses on a passage by passage commentary of each book, followed by a ‘Response’ section that is usually some form of practical application of belief or behavior. For example, in my copy, the ribbon marker was already in Exodus 17:1-7’s ‘Response’ page, and it discussed the question of ‘Why Does God Test His People?’. Jay Sklar’s response includes this wisdom: ‘testing not only gives us an opportunity to show faithfulness; it also helps us to to become more faithful.’ (pg. 578). While I have not yet read the whole thing, Crossway seems to have balanced some well-known scholars with other lesser known ones. Genesis in this volume is covered by Iain Duguid, noted OT scholar currently teaching at Westminster Seminary. Exodus is examined by Covenant Seminary Professor of Old Testament, Jay Sklar, who is a well-known expert on all five books of the Pentateuch. I had not heard of Christine Palmer (Leviticus) or Ronald Bergey (Numbers) before, but Crossway has earned my trust, and I presume their contributions will live up to the standards of others in this series. The commentary is pretty beefy, and the hardcover binding (if my previous volumes are any indication) will need to be handled with care - especially if you are like me, and sometimes try to photocopy pages so you don’t have to carry the whole commentary to a coffee shop or library! All in all, if you are a pastor, Bible student, or lead a Bible study, this series, and this volume, will be a benefit to you.

Excellent, Readable Bible Commentary
Format: Hardcover, Format: Hardcover
I feel more than a little inadequate writing a review of this first volume of the Expository Commentary which uses the English Standard Version (ESV) of the Holy Bible. The ESV has become my favorite Bible translation due to its excellent readability and reliability, thus influencing my decision to order this commentary. Just as readability influences my choice of Bible translations, this commentary also does an excellent job of maintaining readability across all four authors, each one having authored one complete book- Genesis through Numbers. This is a scholarly work and as such it uses references to a large body of additional scholarly works, more than three full pages worth, and lists abbreviations for each with those abbreviations noted throughout the text of the commentary for each book in the volume. These references include ancient as well as more contemporary works, most have English titles and a number are works grounded in the original Hebrew. Another help for any expositor are the ongoing references to other Bible passages that relate to the text of the commentary. Each of these references, and there are thousands of them, are listed in a Scripture Index organized from Genesis to Revelation that require nearly sixty pages at the very back of the volume. Though I’ve not read all 1392 pages, I’ve found editing to be excellent, though I did find one error on page 34 that had no consequence for understanding the meaning. I know many prefer the ease of using digital resources for study due to quick access, portability, and easy storage (I found this resource is also available digitally). I can easily recommend this resource without reservation.
