All the first-born males that come from your herd and from your flock, you shall set apart to Jehovah your God. You shall do no work with the first-born of your bull, nor shear the first-born of your sheep.

then it shall be in the day when he makes his sons to inherit what he has, he may not cause to inherit the son of the beloved first-born before the son of the hated one, he who is truly the first-born.

But he shall acknowledge the son of the hated as the first-born by giving him a double portion of all that he has. For he is the beginning of his strength. The right of the first-born is his.

If a man has two wives, one beloved and another hated, and they have borne him sons, the beloved and the hated; and if the first-born son was of her that was hated,

And it shall be, the first-born whom she bears shall succeed in the name of his dead brother, so that his name may not be put out of Israel.

And there you shall bring your burnt offerings, and your sacrifices, and your tithes, and heave offering of your hand, and your vows, and your free-will offerings, and the first-born of your herds and of your flocks.

You may not eat inside your gates the tithe of your grain or of your wine or of your oil, or the first-born of your herds or of your flock, or any of your vows which you vow, or your free-will offerings or the heave offering of your hand.

And you shall eat before Jehovah your God in the place which He shall choose to place His name there, the tithe of your grain, of your wine, and of your oil, and the first-born of your herds and of your flocks, so that you may learn to fear Jehovah your God always.

The sons that are born to them shall enter into the congregation of Jehovah in their third generation.

His glory is like the first-born of his bull, and his horns are like the horns of the wild ox. With them he shall push the people together to the ends of the earth. And they are the ten thousands of Ephraim, and they are the thousands of Manasseh.

Furthermore, no one born due to an illicit sexual relationship may participate in the assembly of the LORD, including his descendants to the tenth generation.
