Exodus 31:12-18
The Sabbath is the covenant sign that Israel belongs to the Lord who sanctifies them, and the mountain instructions conclude with God giving Moses the tablets of testimony.
12 Yahweh spoke to Moses, saying,
13 “Speak also to the children of Israel, saying, ‘Most certainly you shall keep my Sabbaths; for it is a sign between me and you throughout your generations, that you may know that I am Yahweh who sanctifies you.
14 You shall keep the Sabbath therefore, for it is holy to you. Everyone who profanes it shall surely be put to death; for whoever does any work therein, that soul shall be cut off from among his people.
15 Six days shall work be done, but on the seventh day is a Sabbath of solemn rest, holy to Yahweh. Whoever does any work on the Sabbath day shall surely be put to death.
16 Therefore the children of Israel shall keep the Sabbath, to observe the Sabbath throughout their generations, for a perpetual covenant.
17 It is a sign between me and the children of Israel forever; for in six days Yahweh made heaven and earth, and on the seventh day he rested, and was refreshed.’ ”
18 When he finished speaking with him on Mount Sinai, he gave Moses the two tablets of the covenant, stone tablets, written with God’s finger.
The Sabbath is the covenant sign that Israel belongs to the LORD who sanctifies them, and the mountain instructions conclude with God giving Moses the tablets of testimony.
To command Israel to keep the Sabbath as a covenant sign through their generations, grounding Sabbath holiness in the LORD’s sanctifying work and creation pattern, and to conclude the Sinai instruction section with the giving of the two tablets of testimony written by the finger of God.
Exodus 25-31 contains the LORD's instructions for the tabernacle, its furnishings, priestly garments, consecration rites, sacred oil, incense, and Spirit-equipped craftsmen. Exodus 31:12-18 forms the closing command before the narrative turns to Israel's covenant breach with the golden calf. The Sabbath command stands at the end of the sanctuary instruction to clarify that even tabernacle construction must be governed by covenant holiness. The final mention of the tablets prepares for the crisis of Exodus 32, where the written covenant will be shattered in response to Israel's idolatry.
After appointing Spirit-enabled craftsmen for the tabernacle, the LORD commands Sabbath observance. This placement is crucial: the tabernacle is holy work, but Israel must not violate Sabbath to build it. The mountain-instruction block ends with God giving Moses the tablets of testimony.
The Craftsmen Called by the Spirit and the Sign of the Sabbath
The LORD appoints Spirit-filled craftsmen to build His dwelling, governs their labor by the covenant sign of the Sabbath, and seals the Sinai instructions with stone tablets written by His own hand.
