'Finger' in the Bible

But if I, by the finger of God, send out evil spirits, then the kingdom of God has overtaken you.

And he said, A curse is on you, teachers of the law! for while other men are crushed under the weight of the rules you make for them, you yourselves do not put so much as one finger to them.

And he gave a cry and said, Father Abraham, have mercy on me and send Lazarus, so that he may put the end of his finger in water and put it on my tongue, for I am cruelly burning in this flame.
