Keluaran 31:18

31:18 He gave Moses two tablets of testimony when he had finished speaking with him on Mount Sinai, tablets of stone written by the finger of God. ¹ 

[31:18]  ¹ sn The expression “the finger of God” has come up before in the book, in the plagues (Exod 8:15) to express that it was a demonstration of the power and authority of God. So here too the commandments given to Moses on stone tablets came from God. It too is a bold anthropomorphism; to attribute such a material action to Yahweh would have been thought provoking to say the least. But by using “God” and by stating it in an obviously figurative way, balance is maintained. Since no one writes with one finger, the expression simply says that the Law came directly from God.
