“I the LORD search the heart, I try the reins, even to give every man according to his ways, and according to the fruit of his doings.”
King James Version (KJV)
17:9 The heart - There is nothing so false and deceitful as the heart of man; deceitful in its apprehensions of things, in the hopes and promises which it nourishes, in the assurances that it gives us; unsearchable by others, deceitful with reference to ourselves, and abominably wicked, so that neither can a man know his own heart, nor can any other know that of his neighbour's.
17:11 Hatcheth them not - Having lost them, either by some man that has taken them from her, or by some vermin or wild beast. A fool - Shall lose it again before he dies, and then shall understand what a fool he was.
