'Doest' in the Bible

Then answered the Jews and said unto him, What sign shewest thou unto us, seeing that thou doest these things?

The same came to Jesus by night, and said unto him, Rabbi, we know that thou art a teacher come from God: for no man can do these miracles that thou doest, except God be with him.

They said therefore to him, What sign then doest thou that we may see and believe thee? what dost thou work?

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

for no one does anything in secret and himself seeks to be known in public. If thou doest these things, manifest thyself to the world:

And after the sop Satan entered into him. Then said Jesus unto him, That thou doest, do quickly.
