Amos 4:1

Hear this word, ye (a) kine of Bashan, that [are] in the mountain of Samaria, which oppress the poor, which crush the needy, which say to their masters, (b) Bring, and let us drink.

(a) Thus he calls the princes and governors, who being overwhelmed with the great abundance of God's benefits, forgot God, and therefore he calls them by the name of beasts and not of men.

(b) They encourage those who have authority over the people to oppress them, so that they may have profit by it.
