To Flow By Alongside

παραρυῶμεν

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. Hebrews 2:1

The New American Standard Bible translates it as “so that we do not drift away from it.”

The American Standard version: “lest haply we drift away from them .”

Young’s Literal Translation comes the closest: “lest we may glide aside”

Some see the verb as passive, unmoving as we are “drifted by,” with the idea of one floating in the water as a boat passes by.  The idea is that the lapsed believer does not move along with the group, but instead, stays behind.

παρα (3844) beside, by the side of, alongside of,

ρέω (verb, 4482) to flow

παραρρέω (verb, 3901) gradually drift away, to flow by alongside
