And they rose up in the twilight, to go unto the camp of the Syrians: and when they were come to the edge of the camp of Syria, behold, there was no man there.
Also the firstborn of our sons, and of our cattle, as it is written in the law, and the firstlings of our herds and of our flocks, to bring to the house of our God, unto the priests that minister in the house of our God:
And if it be of an unclean animal, then he shall redeem it according to your valuation, and shall add a fifth part to it: or if it be not redeemed, then it shall be sold according to your valuation.
But the firstling of a cow, or the firstling of a sheep, or the firstling of a goat, you shall not redeem; they are holy: you shall sprinkle their blood upon the altar, and shall burn their fat for an offering made by fire, for a sweet aroma unto the LORD.
Because all the firstborn are mine; for on the day that I struck all the firstborn in the land of Egypt I hallowed unto me all the firstborn in Israel, both man and animal: mine shall they be: I am the LORD.
All the firstborn males that come of your herd and of your flock you shall sanctify unto the LORD your God: you shall do no work with the firstborn of your bullock, nor shear the firstborn of your sheep.
