Matthew Henry's Concise Commentary

25:1-5 The friendship of the wicked is more dangerous than their enmity; for none can prevail against God's people if they are not overcome by their inbred lusts; nor can any enchantment hurt them, but the enticements of worldly interests and pleasures. Here is the sin of Israel, to which they are enticed by the daughters of Moab and Midian. Those are our worst enemies who draw us to sin, for that is the greatest mischief any man can do us. Israel's sin did that which all Balaam's enchantments could not do; it set God against them. Diseases are the fruits of God's anger, and the just punishments of prevailing sins; one infection follows the other. Ringleaders in sin ought to be made examples of justice.
