Hebrews 2:1

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.

Therefore we ought to pay greater attention to the things that were heard, lest perhaps we drift away.

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

Because of this it behoveth `us' more abundantly to take heed to the things heard, lest we may glide aside,

We must pay closer attention, therefore, to what we have heard, so that we do not drift away.
