Exodus 13:18

14 In the future, when your son asks you, ‘What does this mean?’ you are to tell him, ‘With a mighty hand the LORD brought us out of Egypt, out of the house of slavery.

15 And when Pharaoh stubbornly refused to let us go, the LORD killed every firstborn in the land of Egypt, both of man and beast. This is why I sacrifice to the LORD the firstborn male of every womb, but I redeem all the firstborn of my sons.’

16 So it shall serve as a sign on your hand and a symbol on your forehead, for with a mighty hand the LORD brought us out of Egypt.”

17 When Pharaoh let the people go, God did not lead them along the road through the land of the Philistines, though it was shorter. For God said, “If the people face war, they might change their minds and return to Egypt.”

18 So God led the people around by the way of the wilderness toward the Red Sea. And the Israelites left the land of Egypt arrayed for battle.

19 Moses took the bones of Joseph with him because Joseph had made the sons of Israel swear a solemn oath when he said, “God will surely attend to you, and then you must carry my bones with you from this place.”

20 They set out from Succoth and camped at Etham on the edge of the wilderness.

21 And the LORD went before them in a pillar of cloud to guide their way by day, and in a pillar of fire to give them light by night, so that they could travel by day or night.

22 Neither the pillar of cloud by day nor the pillar of fire by night left its place before the people.
