Ulangan 16:3

16:3 You must not eat any yeast with it; for seven days you must eat bread made without yeast, symbolic of affliction, for you came out of Egypt hurriedly. You must do this so you will remember for the rest of your life the day you came out of the land of Egypt.

Ulangan 28:64

28:64 The Lord will scatter you among all nations, from one end of the earth to the other. There you will worship other gods that neither you nor your ancestors have known, gods of wood and stone.
