See Exodus 40:17.

The first day of the first month - It Is generally supposed that the Israelites began the work of the tabernacle about the sixth month after they had left Egypt; and as the work was finished about the end of the first year of their exodus, (for it was set up the first day of the second year), that therefore they had spent about six months in making it: so that the tabernacle was erected one year all but fifteen days after they had left Egypt. Such a building, with such a profusion of curious and costly workmanship, was never got up in so short a time. But it was the work of the Lord, and the people did service as unto the Lord; for the people had a mind to work.

On the first day of the first month,.... Which was the month Nisan, as the Targum of Jonathan expresses it; which was the month the children of Israel came out of Egypt, out of which they had now been a whole year, excepting fourteen days:

shalt thou set up the tabernacle of the tent of the congregation; the tabernacle, which had a tent or covering over it, to which the people were gathered at times for religious service.

On the {a} first day of the first month shalt thou set up the tabernacle of the tent of the congregation.

(a) After that Moses had been 40 days and 40 nights in the mountain, that is, from the beginning of August to the tenth of September, he came down, and caused this work to be done: which when finished, was set up in Abib, half March and half April.

40:2 The time for doing this is, On the first day of the first month - This wanted but fourteen days of a year since they came out of Egypt. Probably the work was made ready just at the end of the year, so that the appointing this day gave no delay. In Hezekiah's time they began to sanctify the temple on the first day of the first month, 2Chr 29:17. The new moon (which by their computation was the first day of every month) was observed by them with some solemnity; and therefore this first new moon of the year was thus made remarkable.

i.e. April.

2. On the first day of the first month-From a careful consideration of the incidents recorded to have happened after the exodus (Ex 12:2; 13:4; 19:1; 20:18; 34:28, &c.), it has been computed that the work of the tabernacle was commenced within six months after that emigration; and consequently, that other six months had been occupied in building it. So long a period spent in preparing the materials of a movable pavilion, it would be difficult to understand, were it not for what we are told of the vast dimensions of the tabernacle, as well as the immense variety of curious and elaborate workmanship which its different articles of furniture required.

the tabernacle-the entire edifice.

the tent-the covering that surmounted it (Ex 40:19).

40:1-15 When a new year begins, we should seek to serve God better than the year before. In half a year the tabernacle was completed. When the hearts of numbers are earnest in a good cause, much may be done in a short time; and when the commandments of God are continually attended to, as the rule of working, all will be done well. The high-priesthood was in the family of Aaron till Christ came, and in Him, the substance of all these shadows, it continues for ever.
