Keil & Delitzsch, on Prov 16:20

“The learned in word shall find good things: and he that trusteth in the Lord is blessed.”

“20 He that giveth heed to the word will find prosperity; And he that trusteth in Jahve, blessed is he! The "word" here is the word κατ ̓ ἐξ., the divine word, for משׂכּיל על־דּבר is the contrast of בּז לדבר, Pro 13:13, cf. Neh 8:13. טוב is meant, as in Pro 17:20, cf. Pro 13:21, Psa 23:6; to give heed to God's word is the way to true prosperity. But at last all depends on this, that one stand in personal fellowship with God by means of faith, which here, as at Pro 28:25; Pro 29:25, is designated after its specific mark as fiducia. The Mashal conclusion אשׁריו occurs, besides here, only at Pro 14:21; Pro 29:18.”
