Hebrews 2:1
King James Version (1769 Blayney revision, with Apocrypha) · Berean Standard Bible
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 (note: Gr. run out as leaking vessels).
We must pay closer attention, therefore, to what we have heard, so that we do not drift away.
