Parallel
Exodus 12:16
Brenton's English Septuagint · Berean Standard Bible
And the first day shall be called holy, and the seventh day shall be a holy convocation to you: ye shall do no servile work on them, only as many things as will [necessarily] be done by every soul, this only shall be done by you.
On the first day you are to hold a sacred assembly, and another on the seventh day. You must not do any work on those days, except to prepare the meals—that is all you may do.
