131 On that day they read from the Book of Moses in the hearing of the people. And in it was found written that no Ammonite or Moabite should ever enter the assembly of God, 2 for they did not meet the people of Israel with bread and water, but hired Balaam against them to curse them--yet our God turned the curse into a blessing. 3 As soon as the people heard the law, they separated from Israel all those of foreign descent.

Commentary on Nehemiah 13:1-9
(Read Nehemiah 13:1-9)
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.
