Exodus 31:18

When Moses had received all the instructions respecting the sanctuary to be erected, Jehovah gave him the two tables of testimony-tables of stone, upon which the decalogue was written with the finger of God. It was to receive these tables that he had been called up the mountain (Exo 24:12). According to Exo 32:16, the tables themselves, as well as the writing, were the work of God; and the writing was engraved upon them (חרוּת from חרת = χαράττειν), and the tables were written on both their sides (Exo 32:15). Both the choice of stone as the material for the tables, and the fact that the writing was engraved, were intended to indicate the imperishable duration of these words of God. The divine origin of the tables, as well as of the writing, corresponded to the direct proclamation of the ten words to the people from the summit of the mountain by the mouth of God. As this divine promulgation was a sufficient proof that they were the immediate word of God, unchanged by the mouth and speech of man, so the writing of God was intended to secure their preservation in Israel as a holy and inviolable thing. The writing itself was not a greater miracle than others, by which God has proved Himself to be the Lord of nature, to whom all things that He has created are subservient for the establishment and completion of His kingdom upon earth; and it can easily be conceived of without the anthropomorphic supposition of a material finger being possessed by God. Nothing is said about the dimensions of the tables: at the same time, we can hardly imagine them to have been as large as the inside of the ark; for stone slab 2 1/2 cubits long and 1 1/2 cubits broad, which must necessarily have been some inches in thickness to prevent their breaking in the hand, would have required the streng…

God is here drawing towards a conclusion of what he had to say to Moses upon the mount, where he had now been with him forty days and forty nights; and yet no more is recorded of what was said to him in all that time than what we have read in the six chapters foregoing. In this, I. He appoints what workmen should be employed in the building and furnishing of the tabernacle (Exo 31:1-11). II. He repeats the law of the sabbath, and the religious observance of it (Exo 31:12-17). III. He delivers to him the two tables of the testimony at parting (Exo 31:18).

31:18 Normally, each party to a covenant received a written copy of the terms of the covenant. So it may be that the two stone tablets were identical, one being God’s copy and the other the people’s copy, to be kept together in the Ark of the Covenant. • finger of God: See 34:28.
