35 Thus says the Lord, Who gives the sun for a light by day, The ordinances of the moon and the stars for a light by night, Who disturbs the sea, And its waves roar (The Lord of hosts is His name): 36 "If those ordinances depart From before Me, says the Lord, Then the seed of Israel shall also cease From being a nation before Me forever." 37 Thus says the Lord: "If heaven above can be measured, And the foundations of the earth searched out beneath, I will also cast off all the seed of Israel For all that they have done, says the Lord. 38 "Behold, the days are coming, says the Lord, that the city shall be built for the Lord from the Tower of Hananel to the Corner Gate. 39 The surveyor's line shall again extend straight forward over the hill Gareb; then it shall turn toward Goath. 40 And the whole valley of the dead bodies and of the ashes, and all the fields as far as the Brook Kidron, to the corner of the Horse Gate toward the east, shall be holy to the Lord. It shall not be plucked up or thrown down anymore forever."

Matthew Henry's Commentary on Jeremiah 31:35-40

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.
