TSK · Exodus 13:12

"You shall not blaspheme God, nor curse a ruler of your people.

"All that opens the womb is mine; and all your livestock that is male, the firstborn of cow and sheep.

"'Only the firstborn among animals, which is made a firstborn to Yahweh, no man may dedicate it; whether an ox or sheep, it is Yahweh's.

for all the firstborn are mine. On the day that I struck down all the firstborn in the land of Egypt I made holy to me all the firstborn in Israel, both man and animal. They shall be mine. I am Yahweh."

Everything that opens the womb, of all flesh which they offer to Yahweh, both of man and animal shall be yours: nevertheless you shall surely redeem the firstborn of man, and you shall redeem the firstborn of unclean animals.

also the firstborn of our sons, and of our livestock, as it is written in the law, and the firstborn of our herds and of our flocks, to bring to the house of our God, to the priests who minister in the house of our God;

The first of all the first fruits of every thing, and every offering of everything, of all your offerings, shall be for the priest: you shall also give to the priests the first of your dough, to cause a blessing to rest on your house.
