“Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip. let: Gr. run out as leaking vessels”
They are said to let the word run out, which hold it not fast when they have heard it. Now as it were pausing with himself and showing to what end and purpose all these things were spoken, to wit, to understand by the excellency of Christ above all creatures, that his doctrine, majesty and Priesthood is most perfect, he useth an exhortation taken from a comparison. He maketh himself an hearer.
