Matthew Henry on Proverbs 17:20
Note, 1. Framing ill designs will be of no advantage to us; there is nothing got by them: He that has a froward heart, that sows discord and is full of resentment, cannot promise himself to get by it sufficient to counterbalance the loss of his repose and reputation, nor can he take any rational satisfaction in it; he finds no good. 2.

Pro 17:16
16 Why the ready money in the hand of the fool;
To get wisdom when he has yet no heart?
The question is made pointed by זה, thus not: why the ready money when...? Is it to obtain wisdom? - the whole is but one question, the reason of which is founded in לבו אין (thus to be accented with Mugrash going before).
(Note: If we write ולב־ with Makkeph, then we have to accentuate לקנות חכמה with Tarcha Munach, because the Silluk word in this writing has…
