12 `Six days thou dost do thy work, and on the seventh day thou dost rest, so that thine ox and thine ass doth rest, and the son of thine handmaid and the sojourner is refreshed;

14 `Three times thou dost keep a feast to Me in a year;

15 the Feast of Unleavened things thou dost keep; seven days thou dost eat unleavened things, as I have commanded thee, at the time appointed [in] the month of Abib; for in it thou hast come forth out of Egypt, and ye do not appear [in] My presence empty;
