'Whence' in the Bible

And whence is this to me, that the mother of my Lord should come to me?

When the unclean spirit has gone out of the man, he goes through dry places seeking rest; and not finding any he says, I will return to my house whence I came out.

From the time that the master of the house shall have risen up and shall have shut the door, and ye shall begin to stand without and to knock at the door, saying, Lord, open to us; and he answering shall say to you, I know you not whence ye are:

and he shall say, I tell you, I do not know you whence ye are; depart from me, all ye workers of iniquity.

And they answered, they did not know whence.
