Three months after leaving Egypt, Israel arrived at Mount Sinai. God told Moses to consecrate the people: 'On the third day the LORD will come down on Mount Sinai in the sight of all the people' (Exodus 19:11). On the morning of the third day, there were thunder and lightning, a thick cloud on the mountain, and a very loud trumpet blast. The mountain was wrapped in smoke because the Lord descended on it in fire. The whole mountain trembled violently.
In this fearsome setting, God gave the Ten Commandments — the moral foundation of Israel's covenant with Him. Then Moses went up the mountain to receive the rest of the Law: civil laws, ceremonial laws, and instructions for building the Tabernacle. The people, terrified, said to Moses, 'You speak to us, and we will listen; but do not let God speak to us, lest we die' (Exodus 20:19).
While Moses was on the mountain receiving the covenant, the people below were already breaking it — crafting a golden calf to worship. This heartbreaking scene revealed how quickly the human heart turns from God, even after witnessing His power.
