Psalms 40:15

Let them be desolate, or amazed; even as Jesus was desolate in his agony, so let his enemies be in their despair when he defeats them. The desolation caused in the hearts of evil spirits and evil men by envy, malice, chagrin, disappointment, and despair, shall be a fit recompense for their cruelty to the Lord when he was in their hands. For a reward of their shame that say unto me, Aha, aha. Did the foul fiend insult over our Lord? Behold how shame is now his reward! Do wicked men today pour shame upon the name of the Redeemer? Their desolation shall avenge him of his adversaries! Jesus is the gentle Lamb to all who seek mercy through his blood; but let despisers beware, for he is the Lion of the tribe of Judah, and "who shall rouse him up?" The Jewish rulers exulted and scornfully said, "Aha, aha; "but when the streets of Jerusalem ran like rivers deep with gore, "and the temple was utterly consumed, "then their house was left unto them desolate, and the blood of the last of the prophets, according to their own desire, came upon themselves and upon their children. O ungodly reader, if such a person glance over this page, beware of persecuting Christ and his people, for God will surely avenge his own elect. Your "ahas" will cost you dear. It is hard for you to kick against the pricks.

That say unto me, Aha, aha - האח האח. See on Psa 35:21 (note).

Let them be desolate - The word here employed means to be astonished or amazed; then, to be laid waste, or made desolate. As used here, it refers to their purposes, and the wish or prayer is that they might be wholly unsuccessful, or that in respect to success they might be like a waste and desolate field where nothing grows. For a reward - The word used here - עקב ‛êqeb - means the end, the last of anything; then, the recompence, reward, wages, as being the end, the result, or issue of a certain course of conduct. That is, in this case, the desolation prayed for would be a proper recompence for their purpose, or for what they said. “Of their shame.” Of their shameful act or purpose; their act as deserving of ignominy. That say unto me, Aha, aha - That use language of reproach and contempt. This is a term of exultation over another; a word of rejoicing at the calamities that come on another; an act of joy over a fallen enemy: Eze 25:3; see Psa 35:21, note; Psa 35:25, note. As understood of the Messiah, this would refer to the taunts and reproaches of his enemies; the exultation which they manifested when they had him in their power - when they felt secure that their vexations in regard to him were at an end, or that they would be troubled with him no more. By putting him to death they supposed that they might feel safe from further molestation on his account. For this act, this note of exultation and joy, on the part of the Jewish rulers, and of the people as stimulated by those rulers, the desolation which came upon them (the utter ruin of their temple, their city, and their nation) was an appropriate reward. That desolation did not go beyond their desert, for their treatment of the Messiah - as the ruin of the sinner in the future world will not go beyond his desert for having rejected the same Messiah as his Saviour.
