Commentary on the Hebrew Text of the Old Testament - Isaiah

Considered the quintessential commentary among all Old Testament commentaries, constantly cited by all other commentators, linguists, and Bible scholars, the "Biblischer Commentar über das Alte Testament," a masterful work of philological research by Johann Friedrich Carl Keil and Franz Julius Delitzsch, is universally recognized as the most complete, serious, and scholarly work ever written on the Old Testament. It is also the best way to approach the complexity of the original meaning of the words used in the Hebrew text. Its main virtue lies in conducting a deep philological analysis of every important word in every important Old Testament text, within its context, and in an accessible way for those who do not master or even have no knowledge of Hebrew.

To achieve this, Keil and Delitzsch base their exegesis on a direct translation from Hebrew of each passage to be commented on, then seeking textual support in ancient translations, such as the Septuagint and the Vulgate. Then, they analyze that text in light of the use and meaning given to that Hebrew word in other passages of the Bible. Afterwards, their research includes discoveries in documentary scientific areas related to Old Testament exegesis, such as history and archaeology. In many cases, they complete their commentary by presenting the interpretation of that text or word by the Church Fathers and the Reformers.
