'Seed' in the Bible

Eli blessed Elkanah and his wife, and said, "Yahweh give you seed of this woman for the petition which was asked of Yahweh." They went to their own home.

He will take the tenth of your seed, and of your vineyards, and give to his officers, and to his servants.

Jonathan said to David, "Go in peace, because we have both sworn in the name of Yahweh, saying, 'Yahweh shall be between me and you, and between my seed and your seed, forever.'" He arose and departed; and Jonathan went into the city.

Swear now therefore to me by Yahweh, that you will not cut off my seed after me, and that you will not destroy my name out of my father's house."
