You are to bring there your burnt offerings and sacrifices, your tenths and personal contributions, your vow offerings and freewill offerings, and the firstborn of your herds and flocks.

Within your gates you may not eat: the tenth of your grain, new wine, or oil; the firstborn of your herd or flock; any of your vow offerings that you pledge; your freewill offerings; or your personal contributions.

You are to eat a tenth of your grain, new wine, and oil, and the firstborn of your herd and flock, in the presence of Yahweh your God at the place where He chooses to have His name dwell, so that you will always learn to fear the Lord your God.

“You must consecrate to the Lord your God every firstborn male produced by your herd and flock. You are not to put the firstborn of your oxen to work or shear the firstborn of your flock.

“If a man has two wives, one loved and the other unloved, and both the loved and the unloved bear him sons, and if the unloved wife has the firstborn son,

when that man gives what he has to his sons as an inheritance, he is not to show favoritism to the son of the loved wife as his firstborn over the firstborn of the unloved wife.

He must acknowledge the firstborn, the son of the unloved wife, by giving him two shares of his estate, for he is the firstfruits of his virility; he has the rights of the firstborn.

His firstborn bull has splendor,
and horns like those of a wild ox;
he gores all the peoples with them
to the ends of the earth.
Such are the ten thousands of Ephraim,
and such are the thousands of Manasseh.
