Números 21

Números 21:9

To be made whole of a serpent is a great sacrament. What is it to be made whole of a serpent by looking upon a serpent? It is to be made whole of death by believing in one dead. And nevertheless Moses feared and fled. What is it that Moses fled from that serpent? What, brethren, save that which we know to have been done in the gospel? Christ died, and the disciples feared and withdrew from that hope wherein they had been. — EXPLANATION OF THE PSALMS 74:4
