Moab hath been at ease from his youth,.... Lived in great peace and prosperity from the time they became a kingdom; being very little disturbed with wars by their neighbours, or very rarely; so that they were in very prosperous and flourishing circumstances, which occasioned that pride and haughtiness they were notorious for.
This is an emblem of unregenerate men; who, though sinners from their birth, and liable to the curse of the law, subject to the stroke of death, and must come to judgment; yet stupid and quite at ease, having no sight of sin, nor feeling of the burden of its guilt, nor grief or trouble for it; no sense of danger, or fear of hell; but in the utmost security: all which arise from ignorance, hardness of heart, profaneness, and infidelity; thoughtlessness about their immortal souls; putting the evil day far from them; and being under the influence of Satan, who keeps his goods in peace:and he hath settled on his lees; a metaphor taken from wine; which, the longer it remains on the lees, the better body it has, and the richer and stronger it is; and denotes the great tranquillity of the Moabites; the riches they were possessed of, and in which they trusted.
