Exodus 34:8-18

8 Immediately, Moses knelt, bowing with his face touching the ground.
9 Then he said, "Lord, please go with us! Even though we are impossible to deal with, forgive our sin and the wrong we have done, and accept us as your own people."
10 The LORD said, "I'm making my promise again. In front of all your people I will perform miracles that have never been done in any other nation in all the world. All the people around you will see how awesome these miracles are that I will perform for you.
11 Do everything that I command today. Then I will force the Amorites, Canaanites, Hittites, Perizzites, Hivites, and Jebusites out of your way.
12 Be careful not to make a treaty with those who live in the land where you're going. This will prove to be a trap to you.

14 (Never worship any other god, because the LORD is a God who does not tolerate rivals. In fact, he is known for not tolerating rivals.)
15 Be careful not to make a treaty with those who live in that land. When they chase after their gods as though they were prostitutes and sacrifice to them, they may invite you to eat the meat from their sacrifices with them.
16 Then your sons will end up marrying their daughters. When their daughters chase after their gods as though they were prostitutes, they'll lead your sons to do the same thing.
17 "Never make an idol.
18 "You must celebrate the Festival of Unleavened Bread. As I commanded you, you must eat unleavened bread for seven days at the appointed time in the month of Abib, because in that month you came out of Egypt.
