'Finger' in the Bible

And this they said, trying him, that they might have whereof to accuse him. But Jesus stooped down, and with his finger wrote on the ground.

And again he stooped down, and with his finger wrote on the ground.

Then saith he to Thomas, Reach hither thy finger, and see my hands; and reach hither thy hand, and put it into my side: and be not faithless, but believing.
