Numbers 12:2

2.And they said, Hath the Lord indeed spoken only by Moses? They pride themselves on their gift of prophecy, which ought rather to have schooled them to humility. But such is the natural depravity of men, not only to abuse the gifts of God unto contempt of their brethren, but so to magnify them by their ungodly and sacrilegious boasting, as to obscure the glory of their Author. Miriam and Aaron had received the spirit of prophecy, in order that the grace of God might shine forth in them; but from thence they raise up clouds to throw darkness upon the light, which was far brighter in Moses. They boast themselves to be prophets; why, then, do they not consider that there was no ground for glorying in this, inasmuch as that, which had been gratuitously bestowed upon them by God, was not their own? Again, why do they not correctly estimate their own insignificance in comparison with the excellency of Moses, so as, by willingly yielding to him, to show that they set at its proper value what God had respectively conferred upon them? Lest, then, the knowledge of those graces which God has intrusted to us, should puff us up with pride and presumption, let us remember that the more each of us has received, the greater obligations are we under to God and our brethren; and let us also reflect how much is wanting, in us, and how much, too, God has conferred on others, so as to prefer to ourselves those whom God has designed to honor.
