Ecclesiastes 7:16-18

Do not be excessively righteous [like those given to self-conceit], and do not be overly wise (pretentious)—why should you bring yourself to ruin? Do not be excessively or willfully wicked and do not be a fool. Why should you die before your time? It is good that you take hold of one thing (righteousness) and also not let go of the other (wisdom); for the one who fears and worships God [with awe-filled reverence] will come forth with both of them.
