Ecclesiastes 7:19

“Wisdom strengtheneth the wise, etc.] Against such extremes as before mentioned; it is a guard about him, as well as a guide unto him; it is a defence unto him, as before observed, (<210712>Ecclesiastes 7:12); and is better than strength of body, or weapons of war, (<210916>Ecclesiastes 9:16,18); and a wise man does greater things by it than a strong man with them, and is safer with it than he can be by them.

We have to distinguish, as is shown under Psa 31:3, the verbs עזז, to be strong, and עוּז, to flee for refuge; תּעז is the fut. of the former, whence מעז, stronghold, safe retreat, protection, and with ל, since עזז means not only to be strong, but also to show oneself strong, as at Eccl 9:20, to feel and act as one strong; it has also the trans. meaning, to strengthen, as shown in Psa 68:29, but here the intrans. suffices: wisdom proves itself strong for the wise man.
