When he beheld the serpent ( גָחָשׁ in all three places of this verse) of brass, he lived. The record is brief and simple in the extreme, and tells nothing but the bare facts. The author of the Book of Wisdom understood the true bearing of those facts when he called the brazen serpent a σύμβολον σωτηρρίας (Numbers 16:6), and when he wrote ὁ ἐπιστραφεὶς οὐ διὰ τὸ θεωρούμενον (the thing he looked at) ἐσώζετο ἀλλὰ διὰ σὲ τὸν πάντων σωτῆρα. At an earlier day Hezekiah had estimated the σύμβολον σωτηρίας at its true value, as being in itself worthless, and under certain circumstances mischievous (see on 2 Kings 18:4).
