וַיַּקְהֵ֣ל מֹשֶׁ֗ה אֶֽת־כָּל־עֲדַ֛ת בְּנֵ֥י יִשְׂרָאֵ֖ל וַיֹּ֣אמֶר אֲלֵהֶ֑ם אֵ֚לֶּה הַדְּבָרִ֔ים אֲשֶׁר־צִוָּ֥ה יְהוָ֖ה לַעֲשֹׂ֥ת אֹתָֽם׃
Então Moisés convocou toda a congregação dos filhos de Israel, e disse-lhes: Estas são as palavras que o SENHOR ordenou que cumprísseis.

Bracketing the Calf Narrative, we return to the regulations concerning the Sabbath, which receive here a different explanation from what was given in 31:12–17. There the stress was on the symbolic nature of the Sabbath day, but in the present context no reason for observance is given. Cassuto understands this as a clarification of the rules of “making” as the Dwelling is about to be constructed.
