'Finger' in the Bible

(Now they were asking this in an attempt to trap him, so that they could bring charges against him.) Jesus bent down and wrote on the ground with his finger.

The other disciples told him, "We have seen the Lord!" But he replied, "Unless I see the wounds from the nails in his hands, and put my finger into the wounds from the nails, and put my hand into his side, I will never believe it!"

Then he said to Thomas, "Put your finger here, and examine my hands. Extend your hand and put it into my side. Do not continue in your unbelief, but believe."
