'Doth' in the Bible

But the princes of the children of Ammon said to Hanun, Thinkest thou that David doth honor thy father, in that he hath sent comforters unto thee? are not his servants come unto thee to search, and to overthrow, and to spy out the land?

And Joab said, Jehovah make his people a hundred times as many as they are: but, my lord the king, are they not all my lord's servants? why doth my lord require this thing? why will he be a cause of guilt unto Israel?
