Numbers 12:3

3.Now the man Moses was very meek. This parenthesis is inserted, in order that we might perceive that God was not moved by any complaint of Moses, to be so greatly wroth with Aaron and Miriam. It is said that “the Lord heard,” that is to say, to undertake the cause in His character of Judge: and it is now added, that He spontaneously summoned the criminals to His tribunal, though no accuser requested that justice should be done him. For this is the, tendency of the eulogium of his meekness, as if Moses had said that he submitted in silence to the wrong, because, in his meekness, he imposed patience on himself. Moreover, he, does not praise his own Virtue for the sake of boasting, but in order to exhort us by his example, and, if it should be our lot to be treated with indignity, quietly and calmly to wait for the judgment of God. For whence does it come that, when any one has injured us, our indignation carries away our feelings in all directions, and our pain boils up without measure, except because we do not think that our ills are regarded by God until we have made loud and boisterous complaints? This passage, then, teaches us that although the good and gentle refrain from reproaches and accusations, God nevertheless keeps watch for them, and, whilst they are silent, the wickedness of the ungodly cries out to, and is heard by, God. Again, the silence of long-suffering itself is more effectual before God than any cries, however loud. But if God does not immediately proceed to execute vengeance, we must bear in mind what is written elsewhere, that the blood of Abel cried out after his death, that the murder which Cain had committed might not be unpunished. (Genesis 4:10.)
