Nehemiah 13:1
On that day they read in the book of Moses in the audience of the people; and therein was found written, that the Ammonite and the Moabite should not come into the congregation of God for ever;
On that day,.... Not when the wall of the city was dedicated, nor quickly after; for it cannot be thought that people should be so corrupted so soon as this chapter shows; but when Nehemiah had governed them twelve years, and had been at Babylon, and was returned again, as appears from Nehemiah 13:6, compared with Nehemiah 2:1,
they read in the book of Moses in the audience of the people; for from the time of the reading of the law by Ezra, Nehemiah 8:1 it became a custom to read the law publicly:
and therein was found written, that the Ammonite and the Moabite should not come into the congregation of the Lord; that is, be admitted to marry with any of the people of Israel; See Gill on "Deuteronomy 23:3".
