So the merchants - lodged without Jerusalem - They exposed their wares for sale on the outside of the walls.

For the merchants and sellers of all kind of ware,.... The Tyrians particularly, Nehemiah 13:16 lodged without Jerusalem once or twice; one sabbath day or two, not being able to get into the city, such strict watch and care being taken to keep the gates shut; this they did, hoping the Jews would come out to them and buy their goods, though they were not admitted to bring them within the city.

Then the merchants and sellers of all kinds of ware remained throughout the night outside Jerusalem, once and twice. Thus, because egress from the city could not be refused to the inhabitants, the rest of the Sabbath was broken outside the gates. Nehemiah therefore put an end to this misdemeanour also.

13:15-22 The keeping holy the Lord's day forms an important object for their attention who would promote true godliness. Religion never prospers while sabbaths are trodden under foot. No wonder there was a general decay of religion, and corruption of manners among the Jews, when they forsook the sanctuary and profaned the sabbath. Those little consider what an evil they do, who profane the sabbath. We must answer for the sins others are led to commit by our example. Nehemiah charges it on them as an evil thing, for so it is, proceeding from contempt of God and our own souls. He shows that sabbath-breaking was one of the sins for which God had brought judgments upon them; and if they did not take warning, but returned to the same sins again, they had to expect further judgments. The courage, zeal, and prudence of Nehemiah in this matter, are recorded for us to do likewise; and we have reason to think, that the cure he wrought was lasting. He felt and confessed himself a sinner, who could demand nothing from God as justice, when he thus cried unto him for mercy.
