Great stress was always laid upon the due observance of the sabbath day, and it was particularly required from the Jews when they were captives in Babylon, because by keeping that day, in honour of the Creator, they distinguished themselves from the worshippers of the gods that have not made the heavens and the earth.
Commenting on Isaiah 58:13-14
If thou turn away thy foot from the sabbath,.... 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.
(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).
