Exodus 19 and 20 record an event that was a great turning point in the life of the Israelites as well as all mankind. These chapters record the giving of the Law by God through Moses to the nation of Israel.

Exodus 19:1,2 says, "In the third month, when the children of Israel were gone forth out of the land of Egypt, the same day came they into the wilderness of Sinai. For they were departed from Rephidim, and were come to the desert of Sinai, and had pitched in the wilderness; and there Israel camped before the mount."

God fulfilled His promise to Moses. When God had called Moses at the burning bush in the wilderness of Sinai, He said, "I will be with thee; and this shall be a token unto thee, that I have sent thee: When thou hast brought forth the people out of Egypt, ye shall serve God upon this mountain" (3:12).

Moses and the Israelites were now at Mount Sinai, thus fulfilling God's promise to him. At Mount Sinai the covenant by which God would deal with them for about the next 1500 years was given.

In other words, this covenant remained in effect until the Lord Jesus Christ was crucified at Calvary, thus changing the order of God's dealings with mankind.

"The law of the Lord is perfect, converting the soul: the testimony of the Lord is sure, making wise the simple" (Ps. 19:7).
