'Finger' in the Bible

They asked this in order to put Him to the test, so that they might have some charge to bring against Him. But Jesus leant forward and began to write with His finger on the ground.

So the rest of the disciples told him, "We have seen the Master!" His reply was, "Unless I see in his hands the wound made by the nails and put my finger into the wound, and put my hand into his side, I will never believe it."

Then He said to Thomas, "Bring your finger here and feel my hands; bring you hand and put it into my side; and do not be ready to disbelieve but to believe."
