He shall not depart out of darkness; the flame shall dry up his branches, and by the breath of his mouth He shall not depart out of darkness; the flame shall dry up his branches, and by the breath of his mouth shall he go away.
Depart - i:e., escape calamity (Job 15:22-23).
Branches - namely, his offspring (Job 1:18-19, Job's sons and daughters slain; Psalms 37:35).
Dry up. The "flame" is the sultry wind in the East, by which plants most full of sap are suddenly shrivelled.
His mouth - i:e., God's wrath (Isaiah 11:4, "With the rod of His mouth, and with the breath of His lips, shall He slay the wicked").
