Psalms 40:15

Let them be desolate for a reward of their shame that say unto me, Aha, aha.

Ver. 15. Let them be desolate for a reward] A poor reward; but such as sin payeth to her servants: "the wages of sin is death." Sin payeth all her servants in black money. See Psalms 35:21. The word here rendered reward signifieth a heel. It is as if the prophet should say, Let one desolation tread upon the heels of another, till they be utterly undone.
