Hebrews 12:15 while overseeing (looking diligently and carefully watching upon and seeing to it) that no one be lacking (be falling short; be living behind or in the rear; = misses out), by wandering away from God's grace and joyous favor; that not any "root of bitterness" : Deut., progressively sprouting upward, would be crowding in to cause disturbance like the spirit of a mob, and then, through means of it, many folks may be stained (polluted; defiled; = the whole community could be contaminated).
