'Multiply' in the Bible

And Shimei had sixteen sons and six daughters; but his brethren had not many children, neither did all their family multiply, like to the children of Judah.

Joab replied, “May the Lord multiply the number of His people a hundred times over! My lord the king, aren’t they all my lord’s servants? Why does my lord want to do this? Why should he bring guilt on Israel?”

And David hath not taken up their number from a son of twenty years and under, for Jehovah said to multiply Israel as the stars of the heavens.
