1. He (God)demanded faithfulness and obedience
2. A new covenant was coming (Jesus).
...the terms I commanded your forefathers when I brought them out of Egypt, out of the iron smelting furnace. I said,"Obey me and do everything I command you, and you will be my people, and I will be your God.
Jeremiah 31: 31-34
31 "The time is coming," declares the Lord, "when I will make a new covenant with the house of Israel and with the house of Judah.
32 It will not be like the covenant I made with their forefathers when I took them by the hand to lead them out of Egypt,because they broke my covenant, though I was a husband to them, declares the LORD.
33 "This is the covenant I will make with the house of Israel after that time," declares the LORD. "I will put my law in their minds and write it on their hearts. I will be their God, and they will be my people.
34 No longer will a man teach his neighbor, or a man his brother, saying, 'Know the LORD,' because they will all know me, from the least of them to the greatest," declares the LORD. "I will forgive their wickedness and will remember their sins no more."
'Call to me and I will answer you and tell you great and unsearchable things you do not know.'
