Isaiah 58:13

If thou turn away thy foot from the sabbath, &c.— Vitringa renders this, If thou turn away thy foot from the sabbath, so as not to study thy pleasure on my holy day, but callest, &c. The meaning is, "If on the sabbath thou shalt abstain from running up and down, from the ordinary occupation and business of human life, in search of profit or pleasure, &c. Isaiah 58:14. Then, &c." For the observation of the sabbath requires rest and spiritual exercise, as the prophet finely teaches us in the subsequent part of this verse; in which he sets forth, in the strongest and most explicit terms, the manner wherein the sabbath-day should be honoured. The foot in Scripture is frequently used for all the labour and business of men: see Proverbs 4:26. Psalms 119:101 and chap. Isaiah 56:2.
