16:6-14 Those who will not be counselled, cannot be helped. More souls are ruined by pride than by any other sin whatever. Also, the very proud are commonly very passionate. With lies many seek to gain the gratification of pride and passion, but they shall not compass proud and angry projects. Moab was famous for fields and vineyards; but they shall be laid waste by the invading army. God can soon turn laughter into mourning, and joy into heaviness. In God let us always rejoice with holy triumph; in earthly things let us always rejoice with holy trembling. The prophet looks with concern on the desolations of such a pleasant country; it causes inward grief. The false gods of Moab are unable to help; and the God of Israel, the only true God, can and will make good what he has spoken. Let Moab know her ruin is very near, and prepare. The most awful declarations of Divine wrath, discover the way of escape to those who take warning. There is no escape, but by submission to the Son of David, and devoting ourselves to him. And, at length, when the appointed time comes, all the glory, prosperity, and multitude of the wicked shall perish.

12. when it is seen that—rather, "When Moab shall have appeared (before his gods; compare Ex 23:15), when he is weary (that is, when he shall have fatigued himself with observing burdensome rites; 1Ki 18:26, &c.), on the high place (compare Isa 15:2), and shall come to his sanctuary (of the idol Chemosh on Mount Nebo) to pray, he shall not prevail"; he shall effect nothing by his prayers [Maurer].
