'Doth' in the Bible

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

And Joab answered, The LORD make his people an hundred times so many more as they be: but, my lord the king, are they not all my lord's servants? why then doth my lord require this thing? why will he be a cause of trespass to Israel?
