Exodus 23:12-14

New Revised Standard Version Catholic Edition

¹² Six days you shall do your work, but on the seventh day you shall rest, so that your ox and your donkey may have relief, and your homeborn slave and the resident alien may be refreshed. ¹³ Be attentive to all that I have said to you. Do not invoke the names of other gods; do not let them be heard on your lips.
