Bible Verses About Token: Consecration of the firstborn

`And it hath been, when thy son asketh thee hereafter, saying, What is this? that thou hast said unto him, By strength of hand hath Jehovah brought us out from Egypt, from a house of servants;

yea, it cometh to pass, when Pharaoh hath been pained to send us away, that Jehovah doth slay every first-born in the land of Egypt, from the first-born of man even unto the first-born of beast; therefore I am sacrificing to Jehovah all opening a womb who are males, and every first-born of my sons I ransom;

and it hath been for a token on thy hand, and for frontlets between thine eyes, for by strength of hand hath Jehovah brought us out of Egypt.'
