2 Peter 3:17

JMNT(i) 17 You, then, beloved ones, being ones by repeated experiences previously acquainted [with this] (or: knowing beforehand by experiences), be constantly on watch, guard, and keep yourselves in custody, lest – at some point being carried (or: led) away together by the deception (or: in straying; or: to deceit) of the unestablished (unprincipled; inordinate; lawless) folks – you could fall out from your own state of fixed firmness (or: steadfastness).
