American Standard Version

23 And Jehovah spake unto Moses, saying, ² Speak unto the children of Israel, and say unto them, The ^[a]set feasts of Jehovah, which ye shall proclaim to be holy convocations, even these are my set feasts. ³ Six days shall work be done: but on the seventh day is a sabbath of solemn rest, a holy convocation; ye shall do no manner of work: it is a sabbath unto Jehovah in all your dwellings.
