Geneva Bible Notes Reformed @genevanotes

Through desire a man, having separated himself, seeketh [and] intermeddleth with all wisdom. (a) He who loves wisdom will separate himself from all impediments, and give himself wholly to seek it.

Pro 18:1 This series of proverbs now turns from the fool to the separatist: The separatist seeketh after his own pleasure; Against all that is beneficial he showeth his teeth. The reflexive נפרד has here the same meaning as the Rabbinical פּרשׁ מן־הצּבּוּר, to separate oneself from the congregation, Aboth ii. 5; נפרד denotes a man who separates himself, for he follows his own counsel, Arab.
