And Moab was sore afraid of the people, because they were many: and Moab was distressed because of the children of Israel.

Wesley's Notes

22:3 Sore afraid - As it was foretold both in general of all nations, Deu 2:25, and particularly concerning Moab, Exo 15:15.

Matthew Henry's Concise Commentary

22:1-14 The king of Moab formed a plan to get the people of Israel cursed; that is, to set God against them, who had hitherto fought for them. He had a false notion, that if he could get some prophet to pray for evil upon them, and to pronounce a blessing upon himself and his forces, that then he should be able to deal with them. None had so great a reputation as Balaam; and Balak will employ him, though he send a great way for him. It is not known whether the Lord had ever spoken to Balaam, or by him, before this; though it is probable he had, and it is certain he did afterwards. Yet we have abundant proof that he lived and died a wicked man, an enemy to God and his people. And the curse shall not come upon us if there is not a cause, even though men utter it. To prevail with Balaam, they took the wages of unrighteousness, but God laid restraint upon Balaam, forbidding him to curse Israel. Balaam was no stranger to Israel's cause; so that he ought to have answered the messengers at once, that he would never curse a people whom God had blessed; but he takes a night's time to consider what he should do. When we parley with temptations, we are in great danger of being overcome. Balaam was not faithful in returning God's answer to the messengers. Those are a fair mark for Satan's temptation, who lessen Divine restraints; as if to go against God's law were only to go without his leave. The messengers also are not faithful in returning Balaam's answer to Balak. Thus many are abused by the flatteries of those about them, and are prevented from seeing their own faults and follies.
