The Sabbath is mentioned again here (cf. Exo. 20:8-11), in relation to the work of building God’s dwelling place, signifying that as God’s people work with Him and for Him, they must learn to rest with Him by enjoying Him and being filled with Him. Keeping the Sabbath is a sign (v. 17) that God’s people work for God not by their own strength but by enjoying Him and being one with Him. It is also an eternal covenant (v. 16) assuring God that we will be one with Him by first enjoying Him and then working with Him, for Him, and in oneness with Him. God first worked and then rested; man first rests and then works (Gen. 2:2 and note Gen. 2:21b). The mentioning of the Sabbath here indicates also that everything related to the tabernacle and its furniture leads us to God’s Sabbath, with its rest and refreshment in the enjoyment of what God has purposed and done.
