Amos 2:8

Fourth, the Israelites failed to return garments taken as collateral for debts owed them. The Law specified that the Israelites could take a garment as a pledge, except the garment of a widow (Deuteronomy 24:17), but they were to return it to the owner before nightfall (Exodus 22:26-27; Deuteronomy 24:10-13; cf. Deuteronomy 24:6; Job 22:6). The Israelites were even taking these garments with them and displaying them at the public feasts honoring whatever god they worshipped.

Fifth, the Israelites had worshipped other gods (cf. Amos 2:4). They were using the wine that they had received as fines, or had extracted from the poor, to honor heathen gods. The proper course of action would have been to drink wine that the worshipper had paid for himself or present it in worship of the true God.
