'Doth' in the Bible

be it known unto you all, and to all the people of Israel, that in the name of Jesus Christ of Nazareth, whom ye crucified, whom God raised from the dead, even in him doth this man stand here before you whole.

And as they went on the way, they came unto a certain water; and the eunuch saith, Behold, here is water; what doth hinder me to be baptized?

As also the high priest doth bear me witness, and all the estate of the elders: from whom also I received letters unto the brethren, and journeyed to Damascus to bring them also that were there unto Jerusalem in bonds to be punished.

Why is it judged incredible with you, if God doth raise the dead?
