THE SECOND ASCENT OF MOSES INTO MOUNT SINAI.

(12-18) The great work still remained to be done. A series of laws had been laid down for the nation and accepted with unanimity (Exodus 24:3; Exodus 24:7). But "quid prosunt leges sine moribus?" It was necessary for the sustentation of the religious life of the people that a sacred polity should be instituted, a form of worship set up, and regulations established with regard to all the externals of religion--holy persons, holy places, rites, ceremonies, vestments, incense, consecration. Moses was directed to ascend into the mount, and hold prolonged communion with God, in order that he might learn the mind of God with respect to all these things. His prolonged stay for "forty days and forty nights" (Exodus 24:18) was necessary to give him a full and complete knowledge of all the details so elaborately set forth in Exodus 25-30, and again in Exodus 35-40, which thenceforth constituted the essentials of the external worship of Israel, whereby the minds and habits of the people were moulded and impressed in a far more efficacious way than could ever have been done by a mere set of abstract propositions, appealing only to the intellect. "Segnius irritant animum demissa per aures, Quam qu? sunt oculis subjecta fidelibus." The Decalogue and the Book of the Covenant had no doubt a considerable share in forming the character of the Hebrew nation; but a larger share must be assigned to the ritual and ceremonial which Moses was now instructed to set up, and which forms the main subject of the remainder of the Book.

(12) Come up to me into the mount, and be there.--After the sacrificial meal, the seventy-four persons engaged in it had descended into the plain of Er-Rahah, and possibly spent some time there, before a second summons came to Moses. This time he was directed to ascend accompanied only by his minister, Joshua (Exodus 24:13), and was warned that his stay was to be a prolonged one in the words, "And be there."

And I will give thee tables of stone . . . --It is remarkable that these are not expressly said, either here or in Exodus 31:18, to have contained the ten commandments. The fact, however, is distinctly stated in Deuteronomy 5:22; and with respect to the second tables, the same is affirmed in Exodus 34:28. The fiction of a double decalogue is thus precluded.

Verses 12-18. - MOSES' ENTRY INTO THE CLOUD, AND FORTY DAYS' COMMUNE WITH GOD. It was necessary now that Moses should receive full directions for the external worship of God, the sanctuary, and the priesthood. Every religion has something tangible and material about it - holy places, holy things, rites, ceremonies, rules, forms, regulations. If man sets himself to devise these things of his own head, he may very easily go wrong, and find his elaborate inventions "an offence" to God. To avoid this - to secure the result that all should be pleasing and acceptable to "the High and Holy One which inhabiteth eternity," it was thought fitting that "patterns" should be shown to Moses of all that was to be made for the worship (Hebrews 8:5), and exact details given him with respect to the material, size, shape, and construction of each. The results are put before us in seven chapters (chs. 25-31.). For the purpose of allowing ample time for the communications which had to be made and of securing that undivided attention which was requisite in order that all should remain fixed in the memory, God summoned his servant to a long and solitary colloquy, on the mountain summit whereon the cloud rested (Exodus 19:18), apart from all his people. Moses, of course, obeyed; but before ascending, arranged with the elders that in his absence Aaron and Hur should have the direction of affairs, and decide all doubtful questions (ver. 14). He then went up the mountain, accompanied for part of the way by Joshua, who is now spoken of as his "minister," or "attendant" (ver. 13). Joshua probably remained with him for six days, while Moses waited for a summons to enter the cloud. On the seventh day the summons came: and Moses, leaving Joshua, entered the cloud, and was hid from the sight of all men. Verse 12. - Come up to me. Moses, apparently, had descended again into the plain, with Aaron and the seventy elders, after the festival was over. (See ver. 14, and compare Exodus 32:1.) He is now commanded to reascend, and be there - i.e., "And continue there" - foreshadowing the length of the stay. Tables of stone, and a law, and commandments, etc. Literally, "Tables of stone, and the law and the commandments which I have written." The three expressions alike refer to the Decalogue, which alone God wrote. That thou mayest teach them. Rather," to teach them." God wrote the commandments on stone, in order to inculcate them with the greater force upon his people.

24:12-18 A cloud covered the mount six days; a token of God's special presence there. Moses was sure that he who called him up would protect him. Even those glorious attributes of God which are most terrible to the wicked, the saints with humble reverence rejoice in. And through faith in the atoning Sacrifice, we hope for greater honour than Moses ever enjoyed on earth. Now we see through a glass darkly, but when he shall appear, then face to face. This vision of God will continue with equal, if not increasing brightness of joy; not for a few days only, but through eternity.And the Lord said unto Moses, come up to me into the mount,.... For as yet Moses was not got up to the top of the mount, only up some part of it with the elders, though at some distance from the people: but now he is bid to come up higher:

and be there; continue there, as he did six days after this:

and I will give thee tables of stone, and a law, and commandments which I have written; that is, the law of the ten commandments, which were written on tables of stone by the Lord himself; he had already spoken them in the hearing of the people, but now he had wrote them, and that in tables of stone; partly for the duration of them, and partly to represent the hardness of the hearts of the Israelites, the stubbornness of their wills to comply with his law, their contumacy and obstinate persistence in disobedience to it:

that thou mayest teach them; these being in hand and sight, would have an opportunity of explaining them to them and inculcating them on their minds, and pressing them to yield an obedience to them.
