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;

And on that day they read in the book of Moses in the hearing of the people: and therein was found written, that the Ammonites and the Moabites should not come in to the church of God for ever:

On that day there was read in the book of Moses, in the ears of the people, and it hath been found written in it that an Ammonite and Moabite doth not come into the assembly of God, unto the age,

On that day there was a reading from the book of Moses in the hearing of the people; and they saw that it said in the book that no Ammonite or Moabite might ever come into the meeting of God;

On that day they read in the book of Moses in the hearing of the people; and therein was found written, that an Ammonite and a Moabite should not enter into the assembly of God for ever;

On that day they read in the scroll of Moses in the audience of the people; and therein was found written, that an Ammonite and a Moabite should not enter into the assembly of God forever,

Now on that day, they read from the book of Moses in the hearing of the people. And in it, there was found written that the Ammonites and the Moabites must not enter the church of God, even for all time,

On that day - Or, "at that time," as in Nehemiah 12:44.
The entire Pentateuch is probably meant by "the Book of Moses".

On that day - I am quite of Calmet's mind that the transaction detailed in this chapter did not immediately succeed the dedication of the walls of Jerusalem. It is most likely that, when this dedication was ended, Nehemiah returned to Babylon, as himself particularly marks, Nehemiah 13:6, for he did return in the thirty-second year of Artaxerxes; and then, after certain days, supposed to be about the term of one year, he got leave to return to Jerusalem to see how matters were conducted: and there he found the evils which he mentions in this chapter, and which he redressed in the manner himself describes. See the introduction to this book.
Should not come into the congregation - That is, Ye shall not form any kind of matrimonial alliance with them. This, and this alone, is the meaning of the law.

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.

Israel was a peculiar people, and not to mingle with the nations. See the benefit of publicly reading the word of God; when it is duly attended to, it discovers to us sin and duty, good and evil, and shows wherein we have erred. We profit, when we are thus wrought upon to separate from evil. Those that would drive sin out of their hearts, the living temples, must throw out its household stuff, and all the provision made for it; and take away all the things that are the food and fuel of lust; this is really to mortify it. When sin is cast out of the heart by repentance, let the blood of Christ be applied to it by faith, then let it be furnished with the graces of God's Spirit, for every good work.

UPON THE READING OF THE LAW SEPARATION IS MADE FROM THE MIXED MULTITUDE. (Nehemiah 13:1-9)
On that day--This was not immediately consequent on the dedication of the city wall and gates, but after Nehemiah's return from the Persian court to Jerusalem, his absence having extended over a considerable period. The transaction here described probably took place on one of the periodical occasions for the public readings of the law, when the people's attention was particularly directed to some violations of it which called for immediate correction. There is another instance afforded, in addition to those which have already fallen under our notice, of the great advantages resulting from the public and periodical reading of the divine law. It was an established provision for the religious instruction of the people, for diffusing a knowledge and a reverence for the sacred volume, as well as for removing those errors and corruptions which might, in the course of time, have crept in.
the Ammonite and the Moabite should not come into the congregation of God for ever--that is, not be incorporated into the Israelitish kingdom, nor united in marriage relations with that people (Deuteronomy 23:3-4). This appeal to the authority of the divine law led to a dissolution of all heathen alliances (Nehemiah 9:2; Ezra 10:3).

Public reading of the law, and separation from strangers. - Nehemiah 13:1. At a public reading of the law, it was found written therein, that no Ammonite or Moabite should come into the congregation of God, because they met not the children of Israel with bread and with water, but hired Balaam to curse them, though God turned the curse into a blessing. This command, found in Deuteronomy 23:4-6, is given in full as to matter, though slightly abbreviated as to form. The sing. ישׂכּר relates to Balak king of Moab, Numbers 22:2., and the suffix of עליו to Israel as a nation; see the explanation of Deuteronomy 23:4.

That day - Not presently after the dedication of the wall and city, but upon a certain day, when Nehemiah was returned from the Persian court to Jerusalem, from which he had been absent for some considerable time, in which some errors and abuses had crept in. Not come - Not be incorporated into the common - wealth of Israel, nor be joined with any Israelite in marriage.
