John Trapp on Mark 5:30-31

Verse 30. That vertue had gone out of him] As heat goeth out of the Sun into the ayre, water, earth, earthly bodies, and yet remains in the Sun; so here. Salienti aquarum fonti undas si tollas, nec exhauritur, nec extenuatur, sed dulcescit: [illegible: 1 word], etiam docendi officio, dulcedinem [illegible: 1 word], non sentiat minutias. A fountain is not drawn dry, but cleared: so skill is not lost by communicating it to others, but increased.
