According to all that I shew thee - The tabernacle and all that pertained to it were to be in strict accordance with the ideas revealed by the Lord to Moses (compare Exodus 25:40; Exodus 26:30; Acts 7:44; Hebrews 8:5). The word here translated "pattern" is also used to denote the plans for the temple which were given by David to Solomon 1-Chronicles 28:11-12, 1-Chronicles 28:19; it is elsewhere rendered "form, likeness, similitude," Deuteronomy 4:16-17; Ezekiel 8:3, Ezekiel 8:10.
The tabernacle - The Hebrew word signifies the "dwelling-place." It here denotes the wooden structure, containing the holy place and the most holy place, with the tent which sheltered it. See Exodus 26:1 note.

After the pattern of the tabernacle - It has been supposed that there had been a tabernacle before that erected by Moses, though it probably did not now exist; but the tabernacle which Moses is ordered to make was to be formed exactly on the model of this ancient one, the pattern of which God showed him in the mount, Exodus 25:40. The word משכן mishcan signifies literally the dwelling or habitation; and this was so called because it was the dwelling place of God; and the only place on the earth in which he made himself manifest. See Clarke's note on Exodus 25:40, and on Exodus 33:7-10.

According to all that I show thee,.... That is, the sanctuary was to be made in all respects exactly according to the view of it that Moses now had upon the mount from God, and which he was to communicate to the workmen for their instruction and direction:
after the pattern of the tabernacle, and of the pattern of all the instruments thereof, even so shall ye make it: and by the "pattern" is not meant an idea of it, impressed on the mind of Moses, or a picture of it which was shown him, but a little edifice representing it in all its parts, a perfect model of it: and so Maimonides (i) says, "Tabnith", the word here used, signifies the structure and disposition of anything, i.e. the form of it in a four square, in roundness, in a triangle, or in any of the like figures, see Hebrews 8:5 and so David had, by the Spirit, a pattern of the temple, and which he gave to his son Solomon, to build according to it, 1-Chronicles 28:11.

According to all that I show thee, after the pattern of the tabernacle--The proposed erection could be, in the circumstances of the Israelites, not of a fixed and stable but of a temporary and movable description, capable of being carried about with them in their various sojournings. It was made after "the pattern" shown to Moses, by which is now generally understood, not that it was an unheard-of novelty, or an entirely original structure, for it is ascertained to have borne resemblance in form and arrangements to the style of an Egyptian temple, but that it was so altered, modified, and purified from all idolatrous associations, as to be appropriated to right objects, and suggestive of ideas connected with the true God and His worship.

According to all that I shew thee - God shewed him an exact plan of it in little, which he must conform to in all points. And God did not only shew him the model, but gave him also particular directions how to frame the tabernacle, according to that model, in all the parts of it. When Moses was to describe the creation of the world, tho' it be such a stately and curious fabrick, yet he gave a very short and general account of it; but when he comes to describe the tabernacle, he doth it with the greatest niceness and accuracy imaginable: for God's church and instituted religion is more precious to him than all the rest of the world. And the scriptures were written not to describe to us the works of nature, (a general view of which is sufficient to lead us to the knowledge of the Creator,) but to acquaint us with the methods of grace, and those things which are purely matters of revelation.
