'Offspring' in the Bible

But you yourself will not be the builder of the house; but your son, the offspring of your body, he it is who will put up a house for my name.

And the Lord sent an angel who put to death all the men of war and the chiefs and the captains in the army of the king of Assyria. So he went back to his country in shame. And when he came into the house of his god, his sons, the offspring of his body, put him to death there with the sword.
