'Finger of God' in the Bible

Then the magicians said to Pharaoh, This is the finger of God. And Pharaoh's heart was hardened, and he did not hearken to them, as LORD had spoken.

And he gave to Moses, when he had made an end of communing with him upon mount Sinai, the two tablets of the testimony, tablets of stone, written with the finger of God.

And LORD delivered to me the two tablets of stone written with the finger of God. And on them [was] according to all the words, which LORD spoke with you in the mount out of the midst of the fire in the day of the assembly.

But if by a finger of God I cast out the demons, then the kingdom of God has come upon you.
