Numbers 12:3

Meek — This is added as the reason why Moses took no notice of their reproach, and why God did so severely plead his cause. Thus was he fitted for the work he was called to, which required all the meekness he had. And this is often more tried by the unkindness of our friends, than by the malice of our enemies. Probably this commendation was added, as some other clauses were, by some succeeding prophet. How was Moses so meek, when we often read of his anger? But this only proves, that the law made nothing perfect.
