JST, Exodus 34:1–2, 14. Compare Exodus 34:1–2, 14; D&C 84:21–26

God again writes the law on tablets of stone prepared by Moses but takes the Melchizedek Priesthood and its ordinances away from the children of Israel. He gives them the law of carnal commandments instead.

1 And the Lord said unto Moses, Hew thee two other tables of stone, like unto the first, and I will write upon them also, the words of the law, according as they were written at the first on the tables which thou brakest; but it shall not be according to the first, for I will take away the priesthood out of their midst; therefore my holy order, and the ordinances thereof, shall not go before them; for my presence shall not go up in their midst, lest I destroy them.

2 But I will give unto them the law as at the first, but it shall be after the law of a carnal commandment; for I have sworn in my wrath, that they shall not enter into my presence, into my rest, in the days of their pilgrimage. Therefore do as I have commanded thee, and be ready in the morning, and come up in the morning unto mount Sinai, and present thyself there to me, in the top of the mount.

Jehovah is one name by which the Old Testament people know the Lord Jesus Christ.

14 For thou shalt worship no other god; for the Lord, whose name is Jehovah, is a jealous God.
