Isaiah 58:13

“If thou turn away thy foot from the sabbath, &c.] From walking and working on that day; or withdrawest thy mind and affections from all worldly things; the affections being that to the mind as the feet are to the body, which carry it here and there. The time of worship, under the Gospel dispensation, is here expressed in Old Testament language, as the service of it usually is in prophetic writings; though its proper name is the Lord’s day, (<660110>Revelation 1:10), and is here instanced in, and put for all religious institutions and services to be attended unto, and which will be with greater strictness in the times referred to: from doing thy pleasure on my holy day; that is, if thou…”

“(Isa 56:2; Neh 13:15-22). The Sabbath, even under the new dispensation, was to be obligatory (Isa 66:23). foot--the instrument of motion (compare Pro 4:27); men are not to travel for mere pleasure on the Sabbath (Act 1:12). The Jews were forbidden to travel on it farther than the tabernacle or temple. If thou keep thy foot from going on thy own ways and "doing thy pleasure," &c. (Exo 20:10-11). my holy day--God claims it as His day; to take it for our pleasure is to rob Him of His own. This is the very way in which the Sabbath is mostly broken; it is made a day of carnal pleasure instead of spiritual "delight." holy of the Lord--not the predicate, but the subject; "if thou call the holy…”

“If thou turn away thy foot from the Sabbath - The evident meaning of this is, that they were sacredly to observe the Sabbath, and not to violate or pollute it (see the notes at Isaiah 56:2). The idea, says Grotius, is, that they were not to travel on the Sabbath day on ordinary journeys. The ‘foot’ is spoken of as the instrument of motion and travel. ‘Ponder the paths of thy feet’ Proverbs 4:26; that is, observe attentively thy goings. ‘Remove thy foot from evil’ Proverbs 4:27; that is, abstain from evil, do not go to execute evil. So here, to restrain the foot from the Sabbath, is not to have the foot employed on the Sabbath; not to be engaged in traveling, or in the ordinary active…”

“If - If thou take no unnecessary journeys, or do any servile works on the sabbath - day. A delight - Performing the duties of it with chearfulness, delighting in the ordinances of it. Holy - Dedicated to God, consecrated to his service. Isaiah 58:14”

“58:13 Like the practice of fasting, the Sabbath was intended to be an expression of self-denial and worship. It consists of delighting in the Lord, trusting him to provide for one’s needs while abstaining from work, and living in obedience to his will.”

“turn: Isa 56:2-6; Exo 20:8-11, Exo 31:13-17, Exo 36:2, Exo 36:3; Deu 5:12-15; Neh 13:15-22; Jer 17:21-27 call: Psa 27:4, Psa 42:4, Psa 84:2, Psa 84:10, Psa 92:1, Psa 92:2 \*title Psa 122:1; Rev 1:10 Isaiah 58:14”

“The third part of the prophecy now adds to the duties of human love the duty of keeping the Sabbath, together with equally great promises; i.e., it adds the duties of the first table to those of the second, for the service of works is sanctified by the service of worship. "If thou hold back thy foot from the Sabbath, from doing thy business on my holy day, and callest the Sabbath a delight, the holy of Jehovah, reverer, and honourest it, not doing thine own ways, not pursuing thy business and speaking words: then wilt thou have delight in Jehovah, and I will cause thee to ride upon the high places of the land, and make thee enjoy the inheritance of Jacob thy forefather, for the mouth of…”
