שָׁמ֣֛וֹר אֶת־י֥וֹם֩ הַשַׁבָּ֖֨ת לְקַדְּשׁ֑֜וֹ כַּאֲשֶׁ֥ר צִוְּךָ֖֣ ׀ יְהוָ֥֣ה אֱלֹהֶֽ֗יךָ
(IV). Observe le jour du Sabbat pour le sanctifier, comme te l’a prescrit l’Éternel, ton Dieu.
Exodus
He [Moshe] cried out to Adonoy, Adonoy showed him a tree and he threw it into the water, and the water became sweet. There He set before them statutes and ordinances, and there He tested them.
