C. F. Keil and Franz Delitzsch on Proverbs 13:7

Pro 13:7

Two proverbs of riches and poverty: -

There is one who maketh himself rich and hath nothing;

There is another who representeth himself poor amid great riches.

A sentence which includes in itself the judgment which Pro 12:9 expresses. To the Hithpa. התכּבּד (to make oneself of importance) there are associated here two others, in the meaning to make oneself something, without anything after it, thus to place oneself so or so, Ewald, §124a. To the clauses with ו there is supplied a self-intelligible לּו.
