Arthur Pink's The Life of David Volume II follows the life of David in 2 Samuel 10 through 1 Chronicles 22. "Moses erred sadly when, instead of trustfully responding promptly unto the Lord's call for him to make known His request unto Pharaoh, he gave way to unbelief and voiced one objection after another (Ex. 3 and 4); nevertheless in the same we may perceive a lovely exemplification of the self-diffidence of those called upon to minister in divine things, and their personal sense of unfitness and utter unworthiness. The two things are quite distinct, though they are found in one and the same incident: the personal failure of Moses, yet his very failure supplying a blessed type of humility in the true servant of God. That which is found in 2 Samuel 10 affords a parallel: the action of David in expressing his condolence to the king of Ammonites supplies a beautiful type of Christ sending forth His servants with a message of comfort for sinners; yet, as we shall see, from a personal viewpoint, David's conduct was to be blamed."
