Jeremiah 8:9

The wise men are ashamed
Of the wisdom of which they boasted, when it would appear to be folly, and unprofitable to them: they are dismayed and taken;
frightened at the calamities coming upon them, and taken as in a snare, as the wise sometimes are in their own craftiness, ( Job 5:13 ) . Lo, they have rejected the word of the Lord;
sent by the prophets, which urged obedience to the law, and is the best explanation of it; but this they despised, and refused it: and what wisdom is in them?
to contemn that, which, if attended to, would have been profitable to them, and the means of making them wise unto salvation; let them therefore boast of their wisdom ever so much, it is certain there can be none in persons of such a spirit and conduct.
