They are inclosed in their own fat— This is a poetical or proverbial speech, to signify haughtiness, as caused by wealth or great prosperity; together with that indulgence of the sensual appetites, and disregard to the duties and doctrines of religion, which is a consequence of such haughtiness, Jeshurun waxed fat, i.e. rich and prosperous; and the consequence was that he kicked; i.e. grew proud, insulting, and luxurious. See Deuteronomy 32:15.; and Psalms 73:7.
