Zephaniah 3:3

Every class does evil, each in its own way. A very full parallel is Ezekiel 22:25-28 (in Ezekiel 22:25 read princes). The "princes" may be the royal house, or the magnates in whose hands lay the judicial and governing power. Ezek. describing the princes says, they are "like a roaring lion ravening the prey; they have devoured souls; they have taken the treasure; they have made her widows many." The "judges" are compared to evening wolves (Habakkuk 1:8), less powerful than the lions but no less insatiable and murderous. Ezekiel 22:27, "wolves ravening the prey, to shed blood, to destroy souls, to get dishonest gain." Judicial corruption and murder are often complained of by the prophets; Isaiah 1:23; Micah 3:11; cf. Jeremiah 22:17; Ezekiel 22:12.

gnaw not the bones till the morrow The term rendered "gnaw the bones" occurs Numbers 24:8, where, however, the word "bones" is expressed; also Ezekiel 23:34, "thou shalt gnaw the sherds thereof." With this sense the clause might mean, evening wolves that gnawed not(the) bones in the morning;the idea being that the wolves having had no prey in the morning were keen from hunger and ferocious in the evening. Others suppose the word to be different from that in Numbers 24:8, and to be allied to an Aramaic root signifying to cut off(a part), hence to reserve, leave over; and render, evening wolves that leave nothing over till the morning, their insatiable voracity devouring everything, hide and hair, at once. It must be acknowledged that this sense of leave overis somewhat conjectural.
