Have mercy upon us, O Lord, have mercy upon us,.... Merit is not pleaded; for, though servants, they knew they were unprofitable ones: but mercy is asked; whether by the awakened sinner, under first convictions, or by the backsliding professor, for forgiveness of sins, under a sense of them, or as under the correcting: and chastising hand of God for them: and which is repeated, to show the state of their case, which requires mercy, and in haste; and the eagerness of their spirit, and the earnestness of their suit, their prayer being the effectual fervent prayer of a righteous man; for we are exceedingly filled with contempt; by reason of meanness in outward circumstances, the common lot of God's people; and therefore are reckoned the faith of the world, and the offscouring of all things: and on account of their religion, which wicked men make a jest of; reckon an engine of state, to keep people in awe of the civil magistrate; or a piece of priestcraft, to serve the lucrative views of a set of men; or as mere cant and enthusiasm, and a gloomy melancholy business, which none but fools will give into; and particularly on account of peculiar doctrines embraced, which are branded as novel, irrational, and licentious; and ordinances, which entirely depend on the sovereign will of the institutor of them. For these things, and the like, contempt was plentifully poured upon them; they had enough of it, and too much, so much that they could not bear it; it was become intolerable and loathsome, and the more, as it had been a long time continued on them. So Aben Ezra and Kimchi interpret the word, rendered "exceedingly", of a long time.
