'Seed' in the Bible

And this bread was named manna by Israel: it was white, like a grain seed, and its taste was like cakes made with honey.

For six years put seed into your fields and get in the increase;

Aaron and his sons are to put these on whenever they go into the Tent of meeting or come near the altar, when they are doing the work of the holy place, so that they may be free from any sin causing death: this is to be an order for him and his seed after him for ever.

Their hands and feet are to be washed. so that they may be safe from death: this is an order to them for ever; to him and his seed from generation to generation.

Have in mind Abraham, Isaac, and Israel, your servants, to whom you gave your oath, saying, I will make your seed like the stars of heaven in number, and all this land will I give to your seed, as I said, to be their heritage for ever.

And the Lord said to Moses, Go forward from this place, you and the people whom you have taken up out of the land of Egypt, to that land about which I made an oath to Abraham, Isaac, and Jacob, saying, To your seed will I give it.
