John Trapp on Proverbs 7:3

Verſ. 3. Binde them upon thy fingers] That thou mayeſt have them alwaies in ſight: as God hath his people, Iſa. 49.16. Behold I have graven thee upon the palms of my hands: thy walls are continually before mee. The Hebrews here refer fingers to action, heart to meditation and retention. Men ſhould have the Law of God at their fingers ends. (Any of us Jews, ſaith Joſephus, being asked of any point of the Law, anſwereth it as readily as if hee had been asked his own name) they ſhould alſo bee doers of the word, and not hearers onely. The hand is [non-Latin text not transcribed], the inſtrument of action.Ariſtot. David lifted up both his hands to the word, as if hee would pull it to him with both hands, as if hee would do the deed in good earneſt.Pſal. 119.48 The Heavens are the work of Gods fingers, Pſal. 8.3. The Law ſhould bee of ours.
