Exodus 13:10 ASV

⁸  And thou shalt tell thy son in that day, saying, It is because of that which Jehovah did for me when I came forth out of Egypt.

⁹  And it shall be for a sign unto thee upon thy hand, and for a memorial between thine eyes, that the law of Jehovah may be in thy mouth: for with a strong hand hath Jehovah brought thee out of Egypt.

¹⁰  Thou shalt therefore keep this ordinance in its season from year to year.

¹¹  And it shall be, when Jehovah shall bring thee into the land of the Canaanite, as he sware unto thee and to thy fathers, and shall give it thee,

¹²  that thou shalt set apart unto Jehovah all that openeth the womb, and every firstling which thou hast that cometh of a beast; the males shall be Jehovah's.
