40 He then Who used humble words with Paul His persecutor, He also used humble sayings with the Pharisee. For so great is the power of humility that even God Who overcomes all did not overcome without it. Humility was able also in the wilderness to bear the burden of the stiff-necked people. For against the people who were more stubborn than all men, was set Moses who was more meek than all men. For God Who needs not anything, when He had set free the people, afterwards had need of the humility of Moses, that this humility might endure the wrath and murmuring of the People that provoked him. For humility alone could endure the gainsayings of that people, which the signs of Egypt and the prodigies (wrought) in the desert could not subdue. For when pride had wrought divisions among the people, humility by its prayer used to close up their divisions. If then the humility of the Stammerer endured six hundred thousand, how much more exceedingly did the humility of Him, Who gave speech to the Stammerer endure? For the humility of Moses is a shadow of the humility of our Lord.
