Exodus 24:12 And the Lord said unto Moses, Come up to me into the mount, and be there: and I will give thee tables of stone, and a law, and commandments which I have written; that thou mayest teach them.
[Patriarchs & Prophets pp 314] As the symbol of God's authority and the embodiment of His will, there was delivered to Moses a copy of the Decalogue engraved by the finger of God Himself upon two tables of stone (Deuteronomy 9:10; Exodus 32:15, 16), to be sacredly enshrined in the sanctuary, which, when made, was to be the visible center of the nation's worship. From a race of slaves the Israelites had been exalted above all peoples to be the peculiar treasure of the King of kings.
God had separated them from the world, that He might commit to them a sacred trust. He had made them the depositaries of His law, and He purposed, through them, to preserve among men the knowledge of Himself. Thus the light of heaven was to shine out to a world enshrouded in darkness, and a voice was to be heard appealing to all peoples to turn from their idolatry to serve the living God. If the Israelites would be true to their trust, they would become a power in the world.
God would be their defense, and He would exalt them above all other nations. His light and truth would be revealed through them, and they would stand forth under His wise and holy rule as an example of the superiority of His worship over every form of idolatry.
Exodus 19:5 Now therefore, if ye will obey my voice indeed, and keep my covenant, then ye shall be a peculiar treasure unto me above all people: for all the earth is mine.
May God add His blessing to the study of His word. “Good night” and God bless!
