Numbers 12 :3

From NBC
The author comments about Moses’ humility (3). True humility consists in a commitment to obeying God’s will to the point of self–denial. Such self–sacrifice can leave a man vulnerable and forced to cast himself on God to protect and sustain him. Further, as he strives to serve God, he discovers his own weaknesses and failings, and in that way reaches a proper view of himself. Humility is not a negative quality (devaluing of self) but a positive commitment to service, supremely exemplified in Christ (Phil. 2:3-8). Moses showed humility in continuing to lead Israel through the desert for forty years, even though it was a burden. He did not defend himself but turned to God, who defends and helps the humble (Pss. 147:6; 149:4; Mt. 5:5; 1 Pet. 5:6). On this occasion, the Lord left Miriam and Aaron in no doubt as he upheld his servant Moses. Thus, Numbers records three ‘complainings’ before Israel was half way to Canaan.
