Charles Ellicott Commentary Amos 4:1

"Hear this word, ye kine of Bashan, that are in the mountain of Samaria, that oppress the poor, that crush the needy, that say unto their lords, Bring, and let us drink." — Amos 4:1 (ASV)

Bashan. This contained the rich pasture-lands east of the Jordan, between Hermon and the mountains of Gilead, where cattle flourished. The phrase “strong bulls of Bashan” (Psalms 22:12) was descriptive of the malignant enemies of the ideal sufferer. The feminine term “kine” refers to the luxurious, self-indulgent women of fashion in Samaria.

Which say to their masters (i.e., their husbands), Bring, and let us drink. Their very debauch being paid for by the robbery of the poor. Some regard the feminine terms as sarcastic epithets, merely expressing effeminacy on the part of men. But this is not a probable explanation.
