Leviticus 23:2-3

BBE(i) 2 Say to the children of Israel, These are the fixed feasts of the Lord, which you will keep for holy meetings: these are my feasts. 3 On six days work may be done; but the seventh day is a special day of rest, a time for worship; you may do no sort of work: it is a Sabbath to the Lord wherever you may be living.
