John Trapp on Matthew 16:9

Verse 9. Neither remember] Tantum didicimus, quantum [illegible: 1 word]. So much we learn as we remember. Our memories Discere, voluit Socrates nihil aliud esse [illegible: 1 word] recordari. Cic. Tusc. [illegible: 1 word]. are naturally like hour-glasses, no sooner filled with good instructions and experiments, then running out again. It must be our prayer to God, that he would put his finger upon the hole, and so make our memories like the pot of Mannah, preserving holy truths in the Ark of the soul.
