Exodus Chapter 13 Verses 11-16  

:11 “And it shall be when the LORD shall bring thee into the land of the Canaanites, as he sware unto thee and to thy fathers, and shall give it thee, 12 That thou shalt set apart unto the LORD all that openeth the matrix, and every firstling that cometh of a beast which thou hast; the males shall be the LORD'S. 13 And every firstling of an ass thou shalt redeem with a lamb; and if thou wilt not redeem it, then thou shalt break his neck: and all the firstborn of man among thy children shalt thou redeem. 14 And it shall be when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto 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 openeth the matrix, being males; but all the firstborn of my children I redeem. 16 And it shall be for a token upon thine hand, and for frontlets between thine eyes: for by strength of hand the LORD brought us forth out of Egypt.” 

“And it shall be when the LORD shall bring thee into the land of the Canaanites, as he sware unto thee and to thy fathers, and shall give it thee, That thou shalt set apart unto the LORD all that openeth the matrix, and every firstling that cometh of a beast which thou hast; the males shall be the LORD'S.”  As a consequence of the LORD’s deliverance of the children of Israel out of Egypt and bringing them into the land of the Canaanite, the children of Israel were to honor the LORD with the firstborn males and the firstlings of beast.   

“And every firstling of an ass thou shalt redeem with a lamb; and if thou wilt not redeem it, then thou shalt break his neck: and all the firstborn of man among thy children shalt thou redeem.”  The principal of redemption is set forth in this verse.  Both the firstborn of man and the firstling of an ass were to be redeemed.  The price of redemption was to offer a lamb for a sacrifice.  All of this typically points us to the redemptive work of Jesus Christ on behalf of the elect as the Lamb of God.  The LORD pointed out to the children of Israel that failure to redeem an ass would sentence the ass to death.  This teaches us that without the redemptive work of Jesus our sentence of eternal death would remain. 

“And it shall be when thy son asketh thee in time to come, saying, What is this? that thou shalt say unto 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 openeth the matrix, being males; but all the firstborn of my children I redeem.”  Once again we see the purpose of the Passover feast and the feast of unleavened bread was to remind those who came out of Egypt and to teach their children and subsequent generations how the Lord delivered the children of Israel out of Egyptian bondage and how he accomplished overcoming Pharaoh’s hardened heart by slaying all the firstborn in the land of Egypt, both the firstborn of man and the firstborn of beasts.  It was for this reason that they were to sacrifice to the Lord all that openeth the matrix, being males; but all the firstborn of the children of Israel are redeemed by sacrificing a lamb instead.   

“And it shall be for a token upon thine hand, and for frontlets between thine eyes: for by strength of hand the LORD brought us forth out of Egypt.”
