Rashi, from Targum Yonasan: They lend to the poor, take security from them and make their garments sheets, and lie on them while eating. "Yatu" is reclining. They used to eat while reclining on the left.

Radak: They are Chovel (take for security) garments from anyone one who does not give like they demand. They eat and drink in the houses of idolatry. "Yatu" ? they lean to recline by every Mizbe'ach, and for food and drink. Reclining is called Hatiyah, for one leans like one who lies down. We find 'Yatu and they recite', 'Heitisi to recite' (Brachos 1:3).

Malbim: This was an increase in idolatry. They are Chovel garments of the poor, and sanctify them for the Mizbe'ach of the Ba'al, to spread them near the Mizbe'ach and recline on them when eating Korbanos to their gods.

Rashi: Their houses of idolatry by the Mizbe'ach.

Rashi: They punish them [and take their] money, and use it to drink wine.

Malbim: Also wine they drank in their idolatry houses to honor the idols ? "Asher Chelev Zevachemu Yochelu Yishtu Yayin Nesicham" (Devarim 32:38). They take money from Tzadikim that they punished monetarily, and use it to drink wine to idolatry. The sin of idolatry is mixed with the sin of theft, plundering Aniyim and the screams of Evyonim.
