'Whence' in the Bible

And when the sabbath was come, he began to teach in the synagogue: and many hearing him were astonished, saying, Whence hath this man these things? and, What is the wisdom that is given unto this man, and what mean'such mighty works wrought by his hands?

And his disciples answered him, Whence shall one be able to fill these men with bread here in a desert place?

David himself calleth him Lord; and whence is he his son? And the common people heard him gladly.
