'Add' in the Bible

But Joab said, "May Yahweh add to the people a hundred times what they are! Are they not, O my lord the king, all of them the king's servants? Why does my lord seek this? Why would he bring guilt to Israel?"

Now see, with great effort I have made provision for the house of Yahweh: 100,000 talents of gold, 1,000,000 talents of silver, and bronze and iron [that] cannot be weighed, for there is an abundance. Also timber and stone I have provided, but to these you should add.
