الأمثال ١٩:٨

8 He that getteth understanding loveth his soul, And he that values reasonableness will acquire good; or, more closely, since this would be the translation of ימצא טוב, Pro 16:20; Pro 17:20 : so it happens, or it comes to this, that he acquires good (= היה למצא); the inf. with ל is here, as at Pro 18:24, the expression of a fut. periphrasticum, as in the Lat. consecturus est. Regarding קנה־לּב, vid., Pro 15:32, and שׁמר תּבוּנה vol. i. p. 119. That the deportment of men is either care for the soul, or the contrary of that, is a thought which runs through the Book of Proverbs.

Those are here encouraged, 1. That take pains to get wisdom, to get knowledge, and grace, and acquaintance with God; those that do so show that they love their own souls, and will be found to have done themselves the greatest kindness imaginable. No man ever hated his own flesh, but loves that, yet many are wanting in love to their own souls, for only those love their souls, and consequently love themselves, aright, that get wisdom, true wisdom. 2. That take care to keep it when they have got it; it is health, and wealth, and honour, and all, to the soul, and therefore he that keeps understanding, as he shows that he loves his own soul, so he shall certainly find good, all good. He that retains the good lessons he has learnt, and orders his conversation according to them, shall find the benefit and comfort of it in his own soul and shall be happy here and for ever.

19:8 It is in our self-interest to acquire wisdom because understanding helps us prosper.
