Ecclesiastes 7:25 in the King James Version
I applied mine heart to know, and to search, and to seek out wisdom, and the reason of things, and to know the wickedness of folly, even of foolishness and madness:
Context
24 That which is, is far off and exceedingly deep. Who can find it out?
25 I turned around, and my heart sought to know and to search out, and to seek wisdom and the scheme of things, and to know that wickedness is stupidity, and that foolishness is madness.
26 I find more bitter than death the woman whose heart is snares and traps, whose hands are chains. Whoever pleases God shall escape from her; but the sinner will be ensnared by her.
