Exodus 13:13 Meaning and Commentary

Exodus 13:13

And every firstling of an ass thou shalt redeem with a lamb,
&c.] Which was given to the priest for it; and according to the Jewish canon F6, it might be redeemed with that only;

``not with a calf, nor with an animal (a goat or a ram, as Bartenora interprets it), nor with a lamb slain, or torn to pieces.''
Jarchi thinks the ass only was to be redeemed, and not the firstling of any other unclean creature, but his reasons are insufficient; all unclean creatures, as horses, camels, dogs, swine are included in it, as should seem from ( Numbers 18:15 ) and this is the rather particularly mentioned, because there was a greater plenty of them than of horses and camels, and because they were very useful creatures; and if these were to be redeemed, then much more those of less value, and less useful. Hence might arise the story and calumny, as some have thought, of the Jews worshipping an ass's head: and if thou wilt not redeem it, then thou shall break its neck;
cut off its head on the back of the neck with a knife or cleaver, such as butchers use, as the Misnah F7, and its commentators, interpret it, so that the owner should have no profit by it: and all the firstborn of man amongst thy children shall thou redeem;
with the price of five shekels of the sanctuary, and within thirty days of the birth of it, ( Numbers 18:16 ) and these being to be redeemed as the unclean beasts were, shows that men are by nature unclean, and even the firstborn, whose names are written in heaven, the elect of God, and need redemption by the blood of the Lamb.

Exodus 13:13 In-Context

11 And it shall be when Jehovah hath brought thee into the land of the Canaanites, as he hath sworn to thee and to thy fathers, and hath given it thee,
12 that thou shalt offer unto Jehovah all that breaketh open the womb, and every firstling that cometh of cattle which is thine: the males [shall be] Jehovah's.
13 And every firstling of an ass shalt thou ransom with a lamb; and if thou do not ransom it, thou shalt break its neck; and every firstborn of a man among thy sons shalt thou ransom.
14 And it shall be when thy son asketh thee in time to come, saying, What is this? that thou shalt say to him, With a powerful hand Jehovah brought us out from Egypt, out of the house of bondage.
15 And it came to pass, when Pharaoh stubbornly refused to let us go, that Jehovah slew all the firstborn in the land of Egypt, both the firstborn of men and the firstborn of cattle: therefore I sacrifice to Jehovah all that breaketh open the womb -- being males; and every firstborn of my children I ransom.
