131 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, 2 because they have not come before the sons of Israel with bread and with water, and hire against them Balaam to revile them, and our God turneth the reviling into a blessing. 3 And it cometh to pass, at their hearing the law, that they separate all the mixed people from Israel.
Matthew Henry's Commentary on Nehemiah 13:1-3
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.
