Leviticus
King James Version (KJV)

“Six days shall work be done: but the seventh day is the sabbath of rest, an holy convocation; ye shall do no work therein: it is the sabbath of the LORD in all your dwellings.”
King James Version (KJV)
23:3 Ye shall do no work therein - So it runs in the general for the sabbath day, and for the day of expiation, #Lev 23:28|, excluding all works about earthly employments whether of profit or of pleasure; but upon other feast days he forbids only servile works, as #Lev 23:7|,21,36, for surely this manifest difference in the expressions used by the wife God must needs imply a difference in the things. In all your dwellings - Other feasts, were to be kept before the Lord in Jerusalem only, whither all the males were to come for that end; but the sabbath was to be kept in all places, both in synagogues, and in their private houses.
