4:12 David commanded. and c.But what a disappointment to Baanah and Rechab, was the sentence which David passed upon them! And such they will meet with, who think to serve the Son of David, by cruelty or injustice: who under colour of religion, outrage or murder of their brethren, think they do God service. However men may now canonize such methods of serving the church and the catholic cause, Christ will let them know another day, that Christianity was not designed to destroy humanity. And they who thus think to merit heaven, shall not escape the damnation of hell.
4:8-12 A person may be glad to obtain his just wishes, and yet really regret the means by which he receives them. He may be sorry for the death of a person by which he is a gainer. These men shed innocent blood, from the basest motives. David justly executed vengeance upon them. He would not be beholden to any to help him by unlawful practices. God had helped him over many a difficulty, and through many a danger, therefore he depended upon him to crown and complete his own work. He speaks of his redemption from all adversity, as a thing done; though he had many storms yet before him, he knew that He who had delivered, would deliver.
