All ye beasts of the field, come to devour, yea, all ye beasts in the forest.
All ye beasts of the field - Gentile idolatrous nations hostile to the Jews, summoned by God to chastise them (Jeremiah 12:7-9; Jeremiah 50:17; Ezekiel 34:5): the Chaldeans, and subsequently the Romans. The mention of the "outcasts of Israel" (Isaiah 56:8) brings in view the outcasting, caused by the sins of their rulers (Isaiah 56:10-12).
Come to devour - namely, Israel.
