Verse 4
Sharp arrows - The Chaldee has, "The strong, sharp arrows are like lightning from above, with coals of juniper kindled in hell beneath." On the juniper, see the note on Job 30:4, where this passage is explained. Fiery arrows, or arrows wrapped about with inflamed combustibles, were formerly used in sieges to set the places on fire. See my notes on Eph 6:16 (note).
