Exodus 31:15-18

31:15 Six days ¹  work may be done, ²  but on the seventh day is a Sabbath of complete rest, ³  holy to the Lord; anyone who does work on the Sabbath day must surely be put to death. 31:16 The Israelites must keep the Sabbath by observing the Sabbath throughout their generations as a perpetual covenant. 31:17 It is a sign between me and the Israelites forever; for in six days ⁴  the Lord made the heavens and the earth, and on the seventh day he rested and was refreshed.’” ⁵ 

31:18 He gave Moses two tablets of testimony when he had finished speaking with him on Mount Sinai, tablets of stone written by the finger of God. ⁶ 

¹ tn This is an adverbial accusative of time, indicating that work may be done for six days out of the week.

² tn The form is a Niphal imperfect; it has the nuance of permission in this sentence, for the sentence is simply saying that the six days are work days – that is when work may be done.

³ tn The expression is שַׁבַּת שַׁבָּתוֹן (shabbat shabbaton), “a Sabbath of entire rest,” or better, “a sabbath of complete desisting” (U. Cassuto, Exodus, 404). The second noun, the modifying genitive, is an abstract noun. The repetition provides the superlative idea that complete rest is the order of the day.

⁴ tn The expression again forms an adverbial accusative of time.

⁵ sn The word “rest” essentially means “to cease, stop.” So describing God as “resting” on the seventh day does not indicate that he was tired – he simply finished creation and then ceased or stopped. But in this verse is a very bold anthropomorphism in the form of the verb וַיִּנָּפַשׁ (vayyinnafash), a Niphal preterite from the root נָפַשׁ (nafash), the word that is related to “life, soul” or more specifically “breath, throat.” The verb is usually translated here as “he was refreshed,” offering a very human picture. It could also be rendered “he took breath” (S. R. Driver, Exodus, 345). Elsewhere the verb is used of people and animals. The anthropomorphism is clearly intended to teach people to stop and refresh themselves physically, spiritually, and emotionally on this day of rest.

⁶ sn The expression “the finger of God” has come up before in the book, in the plagues (Exod 8:15) to express that it was a demonstration of the power and authority of God. So here too the commandments given to Moses on stone tablets came from God. It too is a bold anthropomorphism; to attribute such a material action to Yahweh would have been thought provoking to say the least. But by using “God” and by stating it in an obviously figurative way, balance is maintained. Since no one writes with one finger, the expression simply says that the Law came directly from God.
