Vayikra 23:1-3

Orthodox Jewish Bible

23 And Hashem spoke unto Moshe, saying,

² Speak unto the Bnei Yisroel, and say unto them, Concerning the Mo’adim of Hashem, which ye shall proclaim to be mikra’ei kodesh, even these are My Mo’adim.

³ Sheshet yamim shall work be done; but the yom hashevi’i is the Shabbos of Shabbaton, a mikra kodesh; ye shall do no work therein: it is the Shabbos to Hashem in all your dwellings.
