10:4 But if you refuse to release my people, I am going to bring locusts into your territory tomorrow.
10:14 The locusts went up over all the land of Egypt and settled down in all the territory of Egypt. It was very severe; there had been no locusts like them before, nor will there be such ever again.
10:19 and the Lord turned a very strong west wind, and it picked up the locusts and blew them into the Red Sea. Not one locust remained in all the territory of Egypt.
13:7 Bread made without yeast must be eaten for seven days; no bread made with yeast shall be seen among you, and you must have no yeast among you within any of your borders.
