'Doth' in the Bible

Wherefore Nathan spake unto Bathsheba the mother of Solomon, saying, Hast thou not heard that Adonijah the son of Haggith doth reign, and David our lord knoweth it not?

Go and get thee in unto king David, and say unto him, Didst not thou, my lord, O king, swear unto thine handmaid, saying, Assuredly Solomon thy son shall reign after me, and he shall sit upon my throne? why then doth Adonijah reign?

And the king of Israel said unto Jehoshaphat, There is yet one man, Micaiah the son of Imlah, by whom we may inquire of the LORD: but I hate him; for he doth not prophesy good concerning me, but evil. And Jehoshaphat said, Let not the king say so.
