'Doest' in the Bible

The Jews therefore answered and said unto him, What sign showest thou unto us, seeing that thou doest these things?

the same came unto him by night, and said to him, Rabbi, we know that thou art a teacher come from God; for no one can do these signs that thou doest, except God be with him.

They said therefore unto him, What then doest thou for a sign, that we may see, and believe thee? what workest thou?

His brethren therefore said unto him, Depart hence, and go into Judaea, that thy disciples also may behold thy works which thou doest.

For no man doeth anything in secret, and himself seeketh to be known openly. If thou doest these things, manifest thyself to the world.

And after the sop, then entered Satan into him. Jesus therefore saith unto him, What thou doest, do quickly.
