Therefore we ought to give the more earnest heed to the things that were heard, lest haply we drift away from them.

For this reason there is the more need for us to give attention to the things which have come to our ears, for fear that by chance we might be slipping away.

Δια τουτο πρεπει ημεις να προσεχωμεν περισσοτερον εις οσα ηκουσαμεν, δια να μη εκπεσωμεν ποτε.

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.
