'Finger' in the Bible

They asked this to trap Him, in order that they might have evidence to accuse Him.Jesus stooped down and started writing on the ground with His finger.

So the other disciples kept telling him, “We have seen the Lord!”But he said to them, “If I don’t see the mark of the nails in His hands, put my finger into the mark of the nails, and put my hand into His side, I will never believe!”

Then He said to Thomas, “Put your finger here and observe My hands. Reach out your hand and put it into My side. Don’t be an unbeliever, but a believer.”
