But as for me, when they were sick,.... Or under any disorder or distress of body or mind, when any misfortune or infirmity attended them; meaning Saul and his courtiers, before David was persecuted by them; my clothing was sackcloth; that is, he was grieved, and mourned for them, it being usual to put on sackcloth in time of mourning; see Gen 37:34; I humbled my soul with fasting; on the account of them, giving up himself to prayer for them, as follows: and my prayer returned into mine own bosom; that is, he prayed privately and heartily for them, as for himself; he was constant in it, his heart was in it, and he took delight in it, and he was heard and answered; unless the sense should be, that his prayer was slighted by them, and so returned back to himself, as a present despised is returned; but however it was not without its effect, the good for which he prayed for them was returned by the Lord unto him.
