'Hundred fold' in the Bible

And Isaac sowed in that land, and received in the same year a hundredfold; and Jehovah blessed him.

And Joab said to the king, May Jehovah thy God even add to the people, how many soever they be, a hundredfold, and that the eyes of my lord the king may see it; but why does my lord the king delight in this thing?

And Joab said, Jehovah add to his people, how many soever they be, a hundredfold: are they not all, my lord O king, my lord's servants? why does my lord require this thing? why should he become a trespass to Israel?
