And it came to pass in the first month in the second year, on the first day of the month, that the tabernacle was reared up.

So in the first month of the second year, the first day of the month, the tabernacle was set up.

So on the first day of the first month in the second year the House was put up.

Therefore, in the first month of the second year, on the first day of the month, the tabernacle was put in place.

Et factum est mense primo, anno secundo, prima mensis, erectum filit tabernaculum.

And it came to pass in the first month In all the arrangements, which are here described, it must be especially noted, that Moses obeyed God in such a manner as not to vary in the most trifling point from the form prescribed to him. He therefore so frequently enforces the fact, that he did as God had commanded him; and not without reason, for there is nothing to which men are more prone than to mix up their inventions with God's commands, as if they would be wiser than He is. In order then that the people might know that there was nothing of human invention in all the legal service, Moses so carefully insists on this point, and so often testifes to his obedience. But if so great the Prophet dared to attempt nothing of himself in trifling matters, how great is the audacity and arrogance of those men who arbitrarily invent innumerable figments, whereby God may be worshipped! Let us, however, learn from this passage to embrace with reverence whatever has proceeded from God, whilst we reject whatever men advance of themselves.

On the first day of the month - That is, on the first of the month Nisan Exodus 12:2; Exodus 13:4, one year, wanting fourteen days, after the departure of the Israelites from Egypt. They had been nearly three months in reaching the foot of Mount Sinai Exodus 19:1; Moses had spent eighty days on the mountain Exodus 24:18; Exodus 34:28, and some time must be allowed for what is related in Exodus. 24, as well as for the interval between the two periods which Moses spent on the mountain Exodus. 33:1-23. The construction of the tabernacle and its furniture would thus appear to have occupied something less than half a year.

And it came to pass in the first month in (e) the second year, on the first [day] of the month, [that] the tabernacle was reared up.
(e) After they came out of Egypt, (Numbers 7:1).

And it came to pass in the first month, in the second year,.... Of the departure of the children of Israel out of Egypt:
on the first day of the month, that the tabernacle was reared up; so that this was in the spring of the year, about the vernal equinox, on a new year's day, that this was done, which was beginning the year well: it was within a fortnight of a year after their coming out of Egypt, and when they had been about five months and a half in building the tabernacle; for such a time it seems they were in doing that, and which, considering the many things to be done, and in the winter season, it shows great dispatch. Where was the place, in which the tabernacle was reared up, is not said: it is (d) observed, that near the southwest corner of that part of Mount Sinai, which is called Mount Episteme, there is a little hill called Araone by the Arabs, and by the Greeks the tabernacle of the testimony, where they say Aaron was consecrated, and first performed the offices of the priesthood: probably, says a learned man (e), on this hill was placed the tabernacle of the congregation, which Moses was ordered to place without the camp afar off; but he seems to mistake the tent of Moses, or however the little tabernacle erected before the grand one was made, for this tabernacle in Exodus 33:7 which he seems to refer to; it is more probable that it was now reared up in the midst of the camp of Israel, see Numbers 2:2.

On the day mentioned in Exodus 40:2 the dwelling and court were erected. As not quite nine months had elapsed between the arrival of the Israelites at Sinai, in the third month after the Exodus (Exodus 19:1), and the first day of the second year, when the work was finished and handed over to Moses, the building, and all the work connected with it, had not occupied quite half a year; as we have to deduct from the nine months (or somewhat less) not only the eighty days which Moses spent upon Sinai (Exodus 24:18; Exodus 34:28), but the days of preparation for the giving of the law and conclusion of the covenant (Ex 19:1-24:11), and the interval between the first and second stay that Moses made upon the mountain (ch. 32 and 33). The erection of the dwelling commenced with the fixing of the sockets, into which the boards were placed and fastened with their bolts, and the setting up of the pillars for the curtains (Exodus 40:18). "He (Moses) then spread the tent over the dwelling, and laid the covering of the tent upon the top." By the "covering of the tent" we are to understand the two coverings, made of red rams' skins and the skins of the sea-cow (Exodus 26:14). In analogy with this, את־האלל פּרשׂ denotes not only the roofing with the goats' hair, but the spreading out of the inner cloth of mixed colours upon the wooden frame-work.
