'Finger' in the Bible

They said this to test Him, hoping that they would have grounds for accusing Him. But Jesus stooped down and began writing on the ground with His finger.

Then He stooped down again and started writing on the ground.

So the other disciples kept telling him, “We have seen the Lord!” But he said to them, “Unless I see in His hands the marks of the nails, and put my finger into the nail prints, and put my hand into His side, I will never believe.”

Then He said to Thomas, “Reach here with your finger, and see My hands; and put out your hand and place it in My side. Do not be unbelieving, but [stop doubting and] believe.”
