Charles Spurgeon Commentary Jeremiah 31:35-37

"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: 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. 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." — Jeremiah 31:35-37 (ASV)

Thus saith the LORD, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts is his name: if those ordinances depart from before me, saith the LORD, then the seed of Israel also shall cease from being a nation before me for ever. Thus saith 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, saith the LORD.

Now Israel still stands as a people separate from all others, and there is still before the literal seed of Israel a great and glorious future; but as for the spiritual Israel, who worship God in the Spirit, and have no confidence in the flesh, God will sooner blot out the sun and moon than cast away his people, or any one of them. They shall all be his people, and he shall be their God; he will preserve them, and he will keep his covenant with them forever and ever, blessed be his holy name, the name of Jehovah, the God of the covenant which cannot be broken!

Thus saith the LORD, which giveth the sun for a light by day, and the ordinances of the moon and of the stars for a light by night, which divideth the sea when the waves thereof roar; The LORD of hosts is his name: if these ordinances depart from before me, saith the LORD, then the seed of Israel also shall cease from being a nation before me for ever.

Thus saith the LORD; If heaven above can be measured, and the foundation of the earth searched out beneath, I will also cast off all the seed of Israel for all that they have done, saith the LORD.
