IV. The sins for which God will now reckon with Moab, and which justify God in these severe proceedings against them. 1. It is because they have been secure, and have trusted in their wealth and strength, in their works and in their treasures, v. 7. They had taken a great deal of pains to fortify their cities and make large works about them, and to fill their exchequer and private coffers, so that they thought themselves in as good a posture for war as any people could be and that none durst invade them, and therefore set danger at defiance. They trusted in the abundance of their riches and strengthened themselves in their wickedness, Ps. lii. 7. Now, for this reason, that they may have a sensible conviction of the vanity and folly of their carnal confidences, God will send an enemy that will master their works and rifle their treasures. Note, We forfeit the comfort of that creature which we repose that confidence in which should be reposed in God only. The reed will break that is leaned upon. 2. It is because they have not made a right improvement of the days of the peace and prosperity, v. 11. (1.) They had been long undisturbed: Moab has been at ease from his youth. It was an ancient kingdom before Israel was, and had enjoyed great tranquillity, though a small country and surrounded with potent neighbours. God's Israel were afflicted from their youth (Ps. cxxix. 1, 2), but Moab at ease from his youth. He has not been emptied from vessel to vessel, has not known any troublesome weakening changes, but is as wine kept on the lees, and not racked or drawn off, by which it retains its strength and body. He has not been unsettled, nor any way made uneasy; he has not gone into captivity, as Israel have often done, and yet Moab is a wicked idolatrous nation, and one of the confederates against God's hidden ones, Ps. lxxxiii. 3, 6. Note, There are many that persist in unrepented iniquity and yet enjoy uninterrupted prosperity. (2.) They had been as long corrupt and unreformed: He has settled on his lees; he has been secure and sensual in his prosperity, has rested in it, and fetched all the strength and life of the soul from it, as the wine from the lees. His taste remained in him, and his scent is not changed; he is still the same, as bad as ever he was. Note, While bad people are as happy as they used to be in the world it is no marvel if they are bad as they used to be. They have no changes of their peace and prosperity, therefore fear not God, their hearts and lives are unchanged, Ps. lv. 19.
