35 Thus saith Jehovah, who giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, who stirreth up the sea, so that the waves thereof roar; Jehovah of hosts is his name: 36 If these ordinances depart from before me, saith Jehovah, then the seed of Israel also shall cease from being a nation before me for ever. 37 Thus saith Jehovah: If heaven above can be measured, and the foundations of the earth searched out beneath, then will I also cast off all the seed of Israel for all that they have done, saith Jehovah. 38 Behold, the days come, saith Jehovah, that the city shall be built to Jehovah from the tower of Hananel unto the gate of the corner. 39 And the measuring line shall go out further straight onward unto the hill Gareb, and shall turn about unto Goah. 40 And the whole valley of the dead bodies and of the ashes, and all the fields unto the brook Kidron, unto the corner of the horse gate toward the east, shall be holy unto Jehovah; it shall not be plucked up, nor thrown down any more for ever.

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.
