And it shall come to pass, if thou shalt hearken diligently unto the voice of the LORD thy God, to observe and to do all his commandments which I command thee this day, that the LORD thy God will set thee on high above all nations of the earth:

Now if thou wilt hear the voice of the Lord thy God, to do and keep all his commandments, which I command thee this day, the Lord thy God will make thee higher than all the nations that are on the earth.

And it shall come to pass, if thou shalt hearken diligently unto the voice of Jehovah thy God, to take heed to do all his commandments which I command thee this day, that Jehovah thy God will set thee supreme above all nations of the earth;

'And it hath been, if thou dost hearken diligently to the voice of Jehovah thy God, to observe to do all His commands which I am commanding thee to-day, that Jehovah thy God hath made thee uppermost above all the nations of the earth,

Now if you give ear to the voice of the Lord your God, and keep with care all these orders which I have given you today, then the Lord your God will put you high over all the nations of the earth:

"So then, if you will listen to the voice of the Lord your God, so as to keep and do all of his commandments, which I instruct to you this day, the Lord your God will cause you to be more exalted than all the nations which exist upon the earth.

Et erit, si audiendo audieris vocem Jehovae Dei tui, ut custodias ad faciendum omnia praecepta ejus quae ego paecipio tibi hodie: tunc constituet to Jehova Deus tuus superiorem onmibus gentibus terrae.

And it shall come to pass, if thou shalt hearken. He teaches the same thing as before in different words; but the diversity of expression, as well as the repetition, tends to its confirmation. First, God says that He would deal with them so bountifully that they should excel all other nations; for this is the meaning of the words, that they should be illustrious above all the rest of the world on account of the special blessings of God. He afterwards enumerates the blessings which shall never depart from them, if they persevere in the service of God; and here it must be observed that they are reminded, not only in how many ways God is bountiful towards His servants, but also to how many necessities they are exposed, which require His direct and constant aid; for if we are blessed in the city and in the field, we can no more move a foot than stand still, except by His blessing. Such also is the tendency of the whole list, that a scarcity of all things impends over us at every moment, unless God should continually succor us by remedies sent down from heaven, and that every good thing can only come from that one source.

A comparison of this chapter with Exodus 23:20-23 and Leviticus. 26 will show how Moses here resumes and amplifies the promises and threats already set forth in the earlier records of the Law. The language rises in this chapter to the sublimest strains, especially in the latter part of it; and the prophecies respecting the dispersion and degradation of the Jewish nation in its later days are among the most remarkable in scripture. They are plain, precise, and circumstantial; and the fulfillment of them has been literal, complete, and undeniable.
The Blessing. The six repetitions of the word "blessed" introduce the particular forms which the blessing would take in the various relations of life.

And it shall come to pass, if thou shalt hearken diligently unto the voice of the LORD thy God, to observe [and] to do all his commandments which I command thee this day, that the LORD thy God will (a) set thee on high above all nations of the earth:
(a) He will make you the most excellent of all people.

And it shall come to pass, if thou shalt hearken diligently unto the voice of the Lord thy God,.... 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.

This chapter is a very large exposition of two words, the blessing and the curse. They are real things and have real effects. The blessings are here put before the curses. God is slow to anger, but swift to show mercy. It is his delight to bless. It is better that we should be drawn 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 is 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.

THE BLESSINGS FOR OBEDIENCE. (Deuteronomy. 28:1-68)
if thou shalt hearken diligently unto the voice of the Lord thy God--In this chapter the blessings and curses are enumerated at length, and in various minute details, so that on the first entrance of the Israelites into the land of promise, their whole destiny was laid before them, as it was to result from their obedience or the contrary.

For the purpose of impressing upon the hearts of all the people in the most emphatic manner both the blessing which Israel was to proclaim upon Gerizim, and the curse which it was to proclaim upon Ebal, Moses now unfolds the blessing of fidelity to the law and the curse of transgression in a longer address, in which he once more resumes, sums up, and expands still further the promises and threats of the law in Exodus 23:20-33, and Leviticus 26.
