John Gill's Bible Commentary Ver. 1. And it shall come to pass, if thou shalt hearken diligently unto the voice of the Lord thy God , etc.] In his law, and by his prophets: to observe [and] to do all his commandments, which I command thee this day ; for without observing them to do them, hearing them would be to little purpose, and they were all of them to be observed and done, the lesser and weightier matters of the law as they were commanded by Moses in the name of the Lord, and as they would be taught, explained, and enforced by the prophets: that the Lord thy God will set thee on high above all nations of the earth : as they were in the times of David and Solomon; (see Gill on “ Deuteronomy 26:19”).
Matthew Henry Commentary
Verses 1-14 - This chapter is a very large exposition of two words, the blessing an the curse. They are real things and have real effects. The blessing are here put before the curses. God is slow to anger, but swift to sho mercy. It is his delight to bless. It is better that we should be draw to what is good by a child-like hope of God's favour, than that we be frightened to it by a slavish fear of his wrath. The blessing i promised, upon condition that they diligently hearken to the voice of God. Let them keep up religion, the form and power of it, in their families and nation, then the providence of God would prosper all their outward concerns.
