The Lockman Foundation partnered with John MacArthur, Dr. Abner Chou from Master's University, and many other scholars. They created an updated translation based on the New American Standard Bible of 1995 (NASB95). This new translation is the Legacy Standard Bible.
The LSB is a literal, formal-equivalent Bible translation – designed to be the new standard for future generations of pastors and congregations. For more information on the original language texts used for their translation, refer to the LSB's Frequently Asked Questions on their website.
