'Doth' in the Bible

Then Nathan spake unto Bath-sheba 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 thy handmaid, saying, Assuredly Solomon thy son shall reign after me, and he shall sit upon my throne? why then doth Adonijah reign?

hear thou in heaven thy dwelling-place, and do according to all that the foreigner calleth to thee for; that all the peoples of the earth may know thy name, to fear thee, as doth thy people Israel, and that they may know that this house which I have built is called by my name.

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