'Seed' in the Bible

And they took the head of Ish-bosheth to David in Hebron, and said to the king, Here is the head of Ish-bosheth, the son of Saul your hater, who would have taken your life; the Lord has taken payment for the wrongs of my lord the king from Saul and his seed today.

And when the time comes for you to go to rest with your fathers, I will put in your place your seed after you, the offspring of your body, and I will make his kingdom strong.

Great salvation does he give to his king; he has mercy on the king of his selection, David, and on his seed for ever.

After him was Shammah, the son of Ela the Hararite. And the Philistines came together in Lehi, where there was a bit of land full of seed; and the people went in flight from the Philistines.
