Exodus 13:16

16 This will serve as a sign on your hand and at the front of a headband around your forehead that with a strong hand ADONAI brought us out of Egypt."

Exodus 13:16 In-Context

14 When, at some future time, your son asks you, 'What is this?' then say to him, 'With a strong hand ADONAI brought us out of Egypt, out of the abode of slavery.
15 When Pharaoh was unwilling to let us go, ADONAI killed all the firstborn males in the land of Egypt, both the firstborn of humans and the firstborn of animals. This is why I sacrifice to ADONAI any male that is first from the womb of an animal, but all the firstborn of my sons I redeem.'
16 This will serve as a sign on your hand and at the front of a headband around your forehead that with a strong hand ADONAI brought us out of Egypt."
17 After Pharaoh had let the people go, God did not guide them to the highway that goes through the land of the P'lishtim, because it was close by -God thought that the people, upon seeing war, might change their minds and return to Egypt.
18 Rather, God led the people by a roundabout route, through the desert by the Sea of Suf. The people of Isra'el went up from the land of Egypt fully armed.
