'Doeth' in the Bible

I said of laughter, It is mad; and of mirth, What doeth it?

I know that, whatsoever God doeth, it shall be for ever: nothing can be put to it, nor anything taken from it; and God hath done it, that men should fear before him.

Surely there is not a righteous man upon earth, that doeth good, and sinneth not.

Be not hasty to go out of his presence; persist not in an evil thing: for he doeth whatsoever pleaseth him.

As thou knowest not what is the way of the wind, nor how the bones do grow in the womb of her that is with child; even so thou knowest not the work of God who doeth all.
