Amos 2:7

Dust of the earth on the head of the poor. — Can only mean, as Ewald and Keil interpret: they long to see the poor reduced to such distress that dust is thrown on their heads in token of grief. The meek are defrauded as being too weak to claim their own. The latter part of the verse points to the sensuality of the popular worship, the word “maid” being really the prostitute (Heb. k’dçshah) who was devoted to the lustful ritual of Ashera.[17] This obsccnity is regarded by the prophet as part of a deliberate act of desecration to the name of the Holy One of Israel. Moreover, the relation of “father” and “son” was thereby sullied and degraded. (Comp. Leviticus 18:8; Leviticus 18:15; Leviticus 20:11.)
