Isaiah 58:13

If on account of the sabbaths thou restrain thy foot from doing thy pleasure on that holy day; and call the sabbaths delightful, dedicated to God; and wilt not lift up thy foot for any work; nor utter a word in anger from thy mouth;

If thou turn away thy foot from the sabbath, so as not to do thy pleasure on the holy days, and shalt call the sabbaths delightful, holy to God; if thou shalt not lift up thy foot to work, nor speak a word in anger out of thy mouth,
