'Add' in the Bible

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?

And behold, in my affliction I have prepared for the house of Jehovah a hundred thousand talents of gold, and a thousand thousand talents of silver; and of brass and iron without weight, for it is in abundance; and timber and stone have I prepared; and thou shalt add to it.
