 that rest is a commandment. The Lord commanded us to rest, as he did on the seventh day, the Sabbath, which for Christians, and there's a long history about that, and Pope John Paul II speaks about it, the Sabbath, then the Jewish Sabbath, was taken up into the first day of the week, the Lord's Day, Sunday, which I sometimes play with words. I spell it S-O-N Day, Sunday, as in the Son of God.
