2. He complains of their base ingratitude to him (v. 20): "Shall evil be recompensed for good, and shall it go unpunished? Wilt not thou recompense me good for that evil?" 2 Sam. xvi. 12. To render good for good is human, evil for evil is brutish, good for evil is Christian, but evil for good is devilish; it is so very absurd and wicked a thing that we cannot think but God will avenge it. See how great the evil was that they did against him: They have dug a pit for my soul; they aimed to take away his life (no less would satisfy them), and that not in a generous way, by an open assault, against which he might have an opportunity of defending himself, but in a base, cowardly, clandestine way: they dug pits for him, which there was no fence against, Ps. cxix. 85. But see how great the good was which he had done for them: Remember that I stood before thee to speak good for them; he had been an intercessor with God for them, had used his interest in heaven on their behalf, which was the greatest kindness they could expect from one of his character. He is a prophet and he shall pray for thee, Gen. xx. 7. Moses often did this for Israel, and yet they quarrelled with him, and sometimes spoke of stoning him. He did them this kindness when they were in imminent danger of destruction and most needed it. They had themselves provoked God's wrath against them, and it was ready to break in upon them, but he stood in the gap (as Moses, Ps. cvi. 23) and turned away that wrath. Now, (1.) This was very base in them. Call a man ungrateful and you can call him no worse. But it was not strange that those who had forgotten their God did not know their best friends. (2.) It was very grievous to him, as the like was to David. Ps. xxxv. 13; cix. 4, For my love they are my adversaries. Thus disingenuously do sinners deal with the great intercessor, crucifying him afresh, and speaking against him on earth, while his blood is speaking for them in heaven. See John x. 32. But, (3.) It was a comfort to the prophet that, when they were so spiteful against him, he had the testimony of his conscience for him that he had done his duty to them; and the same will be our rejoicing in such a day of evil. The blood-thirsty hate the upright, but the just seek his soul, Prov. xxix. 10.
