'Doest' in the Bible

Son of man, hath not the house of Israel, the rebellious house, said unto thee, What doest thou?

How weak is thy heart, saith the Lord Jehovah, seeing thou doest all these things, the work of a whorish woman, under no restraint;

And the people said unto me, Wilt thou not tell us what these things are to us, which thou doest?
