'Firstborn Males' in the Bible

you are to dedicate to the LORD everything that first opens the womb. All the firstborn males of your livestock belong to the LORD.

Yahweh said to Moses, "Number all the firstborn males of the children of Israel from a month old and upward, and take the number of their names.

And take the Levites for me -- I am the Lord -- instead of all the firstborn males among the Israelites, and the livestock of the Levites instead of all the firstborn of the livestock of the Israelites."

So Moses numbered all the firstborn males among the Israelites, as the Lord had commanded him.

And all the firstborn males by the number of names, from a month old and upward, of those that were numbered of them, were twenty and two thousand two hundred and threescore and thirteen.

"Take the Levites instead of all the firstborn males among the Israelites, and the livestock of the Levites instead of their livestock. And the Levites will be mine. I am the Lord.

And for the redemption of the 273 firstborn males of the Israelites who exceed the number of the Levites,

From the firstborn males of the Israelites he collected the money, 1,365 shekels, according to the sanctuary shekel.

For all the firstborn males among the Israelites are mine, both humans and animals; when I destroyed all the firstborn in the land of Egypt I set them apart for myself.

The firstborn of every womb which they present to the Lord, whether human or animal, will be yours. Nevertheless, the firstborn sons you must redeem, and the firstborn males of unclean animals you must redeem.

All the firstborn males that are born of your herd and of your flock you shall sanctify to Yahweh your God: you shall do no work with the firstborn of your herd, nor shear the firstborn of your flock.
