The Fiery Serpents. This incident is alluded to by Paul in 1 Corinthians 10:9. The serpents are described as fiery by reason of the inflammation caused by their bite. The means whereby the injury they inflicted was remedied was perhaps originally an instance of sympathetic magic inverted (like the cure of a dog's bite by a hair of the dog), though in antiquity serpents were widely credited with healing virtues in general, and were by the Greeks associated with Asclepius. The writer of Nu. naturally assigns the cure of the snake-bite not to magic but to Yahweh (cf. Wis_16:5; Wis_16:7). It is held by several scholars that the present story is mainly an æ tiological legend (p. 134) to explain the practice of the serpent-worship recorded in 2 Kings 18:4. By our Lord the uplifting of the brazen serpent was regarded as a symbol of His crucifixion (Judges 3:14).
4. To compass, etc.: this connects with Numbers 20:14-21.
Numbers 21:5. light: better, contemptible.
