After the Ten Commandments, God gave Moses laws for everyday life — about servants, injuries, property, honesty in court and care for the poor. These chapters show that God cares about how we treat people on ordinary days. He commanded kindness to the stranger: “you know the heart of a stranger, because you were strangers in the land of Egypt.” He told them not to afflict the widow or the fatherless, for He hears their cry.
God also gave Israel three yearly feasts to come before Him — the Feast of Unleavened Bread, the Feast of Harvest and the Feast of Ingathering. He promised to send His Angel before them to guard them on the way and bring them into the land, and He told them to listen to His voice and to serve only the LORD.
Moses wrote down the words of the LORD, built an altar with twelve pillars for the twelve tribes, and offered sacrifices. He read the Book of the Covenant to the people, and they said, “All that the LORD has said we will do, and be obedient.” Then Moses sprinkled the blood on the people and said, “This is the blood of the covenant which the LORD has made with you according to all these words.”
Moses, Aaron, Nadab, Abihu and seventy elders went up the mountain, “and they saw the God of Israel.” Under His feet was something like a paved work of sapphire stone. “So they saw God, and they ate and drank.” Then Moses went up into the cloud and stayed forty days and forty nights. At the Last Supper Jesus echoed this moment: “This cup is the new covenant in My blood, which is shed for you.”
