35 Thus saith Jehovah, who giveth the sun for light by day, the ordinances of the moon and of the stars for light by night, who stirreth up the sea so that the waves thereof roar,—Jehovah of hosts is his name: 36 If those ordinances depart from before me, saith Jehovah, the seed of Israel also shall cease from being a nation before me for ever. 37 Thus saith Jehovah: If the heavens above can be measured, and the foundations of the earth searched out beneath, I will also cast off the whole seed of Israel, for all that they have done, saith Jehovah.

Matthew Henry's Commentary on Jeremiah 31:35-37

Commentary on Jeremiah 31:35-40

(Read Jeremiah 31:35-40)

As surely as the heavenly bodies will continue their settled course, according to the will of their Creator, to the end of time, and as the raging sea obeys him, so surely will the Jews be continued a separate people. Words can scarcely set forth more strongly the restoration of Israel. The rebuilding of Jerusalem, and its enlargement and establishment, shall be an earnest of the great things God will do for the gospel church. The personal happiness of every true believer, as well as the future restoration of Israel, is secured by promise, covenant, and oath. This Divine love passes knowledge; and to those who take hold upon it, every present mercy is an earnest of salvation.
