13 But as for me, when they were ill I put on the clothing of sorrow: I went without food and was sad, and my prayer came back again to my heart. 14 My behaviour was as if it had been my friend or my brother: I was bent low in grief like one whose mother is dead. 15 But they took pleasure in my trouble, and came together, yes, low persons came together against me without my knowledge; they never came to an end of wounding me.
Matthew Henry's Commentary on Psalm 35:13-15
Commentary on Psalm 35:11-16
(Read Psalm 35:11-16)
Call a man ungrateful, and you can call him no worse: this was the character of David's enemies. Herein he was a type of Christ. David shows how tenderly he had behaved towards them in afflictions. We ought to mourn for the sins of those who do not mourn for themselves. We shall not lose by the good offices we do to any, how ungrateful soever they may be. Let us learn to possess our souls in patience and meekness like David, or rather after Christ's example.
