31:18 And he gave unto Moses, when he had made an end of communing with him upon mount Sinai, two tables {i} of testimony, tables of stone, written with the finger of God.
(i) By which he declared his will to his people.
31:18 These tables of stone, were not prepared by Moses, but probably by the ministry of angels. They were written with the finger of God - That is, by his will and power immediately, without the use of any instrument. They were written in two tables, being designed to direct us in our duty, towards God, and towards man. And they were called tables of testimony, because this written law testified the will of God concerning them, and would be a testimony against them if they were disobedient.
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, 2Co 3:3.
