John Gill's Exposition of the Whole Bible
Jeremiah 17:24
And it shall come to pass,.... Or, "yet it shall come to pass" f; so it shall be, notwithstanding all former disobedience and rebellion:
if ye diligently hearken unto me, saith the Lord; or, "in hearing hear" g; hearken attentively, and readily obey the command given, before mentioned, so as
to bring in no burden through the gates of this city on the sabbath day; to be bought or sold, or to be wrought on or with; and so likewise to carry nothing out of their houses or city, which, though not expressed, is understood as before; and this respects not only the city of Jerusalem, but all other cities and towns in Judea; for the word of the Lord, concerning this matter, was sent to all Judah, the whole land of Judea, Jeremiah 17:20;
but hallow the sabbath day, to do no work therein; one part of the sanctification of the sabbath lay in a cessation from all servile work, though not wholly, but also in the observance of religious worship, and the one was in order to the other; for, unless they abstained from worldly business, they could not be at leisure to attend divine service.
