And Moses made a serpent of bronze, and put it upon a pole, and it came to pass, that if a serpent had bitten any man, when he beheld the serpent of bronze, he lived.
All Commentaries on Numbers 21:9 Go To Numbers 21
Justin Martyr
AD 165
Tell me, did not God, through Moses, forbid the making of an image or likeness of anything in the heavens or on earth? Yet didn’t he himself have Moses construct the brazen serpent in the desert? Moses set it up as a sign by which those who had been bitten by the serpents were healed. In doing so, was Moses not free of any sin? By this, as I stated above, God through Moses announced a mystery by which he proclaimed that he would break the power of the serpent, who prompted the sin of Adam. He promises that he would deliver from the bites of the serpent (that is, evil actions, idolatries and other sins) all those who believe in him who was to be put to death by this sign, namely, the cross.
