The Golden Calf

18 And He giveth unto Moses, when He finisheth speaking with him in mount Sinai, two tables of the testimony, tables of stone, written by the finger of God.

Matthew Henry's Commentary on Exodus 31:18

Commentary on Exodus 31:18

(Read Exodus 31:18)

The law was written in tables of stone, to show how lasting it is: to denote likewise the hardness of our hearts; one might more easily write on stone, than write any thing good on our corrupt natural hearts. It was written with the finger of God; by his will and power. God only can write his law in the heart: he gives a heart of flesh; then, by his Spirit, which is the finger of God, writes his will in the heart, 2 Corinthians 3:3.
