Verse 15. - Let them be desolate for a reward of their shame; rather, by reason of their shame (Kay, Alexander, Revised Version). Let the shame and disgrace that attach to them (ver. 14) cause them to be desolate, or deserted of all. That say unto me, Aha, aha! (comp. Psalm 35:21, 25).

40:11-17 The best saints see themselves undone, unless continually preserved by the grace of God. But see the frightful view the psalmist had of sin. This made the discovery of a Redeemer so welcome. In all his reflections upon each step of his life, he discovered something amiss. The sight and sense of our sins in their own colours, must distract us, if we have not at the same time some sight of a Saviour. If Christ has triumphed over our spiritual enemies, then we, through him, shall be more than conquerors. This may encourage all that seek God and love his salvation, to rejoice in him, and to praise him. No griefs nor poverty can render those miserable who fear the Lord. Their God, and all that he has or does, is the ground of their joy. The prayer of faith can unlock his fulness, which is adapted to all their wants. The promises are sure, the moment of fulfilment hastens forward. He who once came in great humility, shall come again in glorious majesty.Let them be desolate for a reward of their shame,....

that say unto me, Aha, aha; words expressive of joy, Psalm 35:21, exulting at his miseries and sufferings on the cross, Matthew 27:39; so the Targum,

"we have rejoiced at his destruction, with joy at his affliction.''
