Exodus 31:18
And he gave unto Moses, when he had made an end of communing with him upon mount Sinai, two tables of testimony, tables of stone, written with the finger of God.
And he gave unto Moses, when he had made an end of communing with him on Mount Sinai,.... After all those laws, orders, and instructions before related, which having done, he ceased to converse with him any longer in that manner he had, and at parting gave him
two tables of testimony; the two tables of the law, which is a testimony of the will of God, and contained the duty of the Israelites both towards God and man, and are reducible to these two, love to God, and love to our neighbour: five of the commands of the decalogue were written on one table, and five on the other; or it may be rather four on one table, the first being the largest, and containing the duty owing to God, and six on the other, which regard the duty of men one to another; so Orpheus the Heathen poet, speaking of the law of Moses, calls it diplaka yesmon {s}. "Tables of stone"; the Targum of Jonathan will have them to be of the sapphire stone, from the throne of glory; the paraphrast seems to have respect to Exodus 24:10 and, with as little appearance of truth, says their weight was forty seahs; it is more probable they were of marble stone, of which there were great quantities in Mount Sinai. Dr. Shaw says {t} that part of Mount Sinai, which lies to the westward of the plain of Rephidim, consists of a hard reddish marble like "porphyry", but is distinguished from it by the representations of little trees and bushes, which are dispersed all over it. The naturalists call this sort of marble "embuscatum", or "bushy marble"; some think Sinai had its name from thence {u}. This may denote the firmness, stability, and duration of the law, not as in the hands of Moses, from which these tables were cast and broke, but as in the hands of Christ, and laid up in him the ark of the covenant, the fulfilling end of the law for righteousness: and it may also figure the hardness of man's heart, which is destitute of spiritual life, obdurate and impenitent, stupid, senseless and ignorant, stubborn and inflexible, and not subject to the law of God, and on which no impressions can be made but by the power and grace of God:
written with the finger of God: by God himself, and not by an angel, or by any creature or instrument: and it is by the finger of God, the Spirit, grace, and power of God, that the laws of God are put into the inward part, and written on the heart, to which the apostle refers, 2 Corinthians 3:3. This account is given by way of transition to what is recorded in the next chapter.
