Ye have lived in pleasure; luxuriously and deliciously, giving up yourselves to your sensual appetites, Amos 6:4-6 Luke 16:19,25. On the earth; where you place your happiness without looking higher, and from whence you fetch your delights, Philippians 3:19. And been wanton: the same word is used 1 Timothy 5:6; it seems to imply effeminate, lascivious behaviour, as the effect of their riotous living. Ye have nourished your hearts: either by a Hebrew phrase, ye have nourished your hearts, for ye have nourished yourselves, Esther 6:6 Job 10:13; or, ye have cheered up and encouraged your hearts in your luxury by pampering your flesh, \Luke 12:19\ and feeding not to the satisfaction of nature, but the inflaming of your lusts. As in a day of slaughter; either securely, and without fear of the destruction coming upon you, as sheep graze quietly, though by and by to be brought to the shambles; or rather, in a day of slaughter, i.e. in a day of solemn feasting, when many beasts were killed in sacrifice, on which they were wont to feast, Proverbs 7:14, Proverbs 17:1. They made every day a feasting day, and that, too, lavishing out other men's dues upon their own flesh, and sparing from their labourers that they might spend upon their lusts. This he brings to aggravate their sin.
