Take ye from among you an offering. I have introduced a passage from chapter 35, wherein Moses again requires what he had before prescribed; but he goes more into detail, and treats at greater length of the parts of the tabernacle. In the former passage he employed a verb, where he here uses a noun, "willing or voluntary of heart." There is, however, no ambiguity in the meaning; since in both places God requires a cheerful zeal, so that they may not only contribute abundantly, but willingly. He will afterwards use a different form of expression, viz., that they did their duty, whose heart roused, or stirred them up, so as to distinguish them from the indifferent and slow. -- 5:21.

An offering - A terumah or heave-offering; see Leviticus 7:1, etc. , Exodus 35:6
See, on these metals and colors, Exodus 25:3 (note), Exodus 25:4 (note), etc.

Take ye from amongst you an offering unto the Lord,.... That is, they were to take a part of their substance, of what they were possessed of, every man according to his ability, out of what he had in his hand that was suitable, and present it as a freewill offering to the Lord, for the use of the tabernacle to be built, and the service of it:
whosoever is of a willing heart; that is, of a generous and liberal disposition:
let him bring it, an offering of the Lord; or an offering to him, otherwise not; if brought niggardly and grudgingly it would not be acceptable, for God loves a willing and cheerful giver:
gold, silver, and brass: here and in the four following verses, the several things are particularly mentioned, which would be wanted in building the tabernacle, and in the service of it, and therefore would be acceptable; and they being exactly the same, and delivered in the same words and in the same order as in Exodus 25:3 the reader is referred to the notes there.
