AKJV(i)
14 And it shall be when your son asks you in time to come, saying, What is this? that you shall say to him, By strength of hand the LORD brought us out from Egypt, from the house of bondage:
15 And it came to pass, when Pharaoh would hardly let us go, that the LORD slew all the firstborn in the land of Egypt, both the firstborn of man, and the firstborn of beast: therefore I sacrifice to the LORD all that opens the matrix, being males; but all the firstborn of my children I redeem.
16 And it shall be for a token on your hand, and for frontlets between your eyes: for by strength of hand the LORD brought us forth out of Egypt.
