Exodus 13:16

16 This ceremony will be like a mark branded on your hand or your forehead. It is a reminder that the power of the LORD ’s mighty hand brought us out of Egypt.”

Exodus 13:16 In-Context

14 “And in the future, your children will ask you, ‘What does all this mean?’ Then you will tell them, ‘With the power of his mighty hand, the LORD brought us out of Egypt, the place of our slavery.
15 Pharaoh stubbornly refused to let us go, so the LORD killed all the firstborn males throughout the land of Egypt, both people and animals. That is why I now sacrifice all the firstborn males to the LORD —except that the firstborn sons are always bought back.’
16 This ceremony will be like a mark branded on your hand or your forehead. It is a reminder that the power of the LORD ’s mighty hand brought us out of Egypt.”
17 When Pharaoh finally let the people go, God did not lead them along the main road that runs through Philistine territory, even though that was the shortest route to the Promised Land. God said, “If the people are faced with a battle, they might change their minds and return to Egypt.”
18 So God led them in a roundabout way through the wilderness toward the Red Sea. Thus the Israelites left Egypt like an army ready for battle.
