Nineteenth-century German theologians Carl Friedrich Keil and Franz Delitzsch wrote one of the most popular and extensive commentaries on the Old Testament. Today their Commentary on the Old Testament is still held in esteem by conservative theological circles for its rigorous scholarship and sound theological judgment. Beginning with the nature and format of the Old Testament, this evangelical commentary examines historical and literary aspects of the text, as well as grammatical and philological issues. Hebrew words and grammar are used, but usually in context, so you can follow the train of thought.

The Keil and Delitzsch Commentary on the Old Testament is the 1996 revised edition from Hendrickson. While the content is unchanged, it features a number of enhancements to the text. Arabic has been transliterated, biblical references have been changed from Roman to Arabic numerals and long paragraphs have been broken into shorter ones so that the work is easier to read.
