1 John 2:19
These antichrists left our group [i.e., withdrew their fellowship from us], but they were not [really a part] of us, for if they had been, they would have continued [to participate] with us. But, by their leaving us, it proved that none of them were [really] a part of our group [after all].
Jude 1:12
These people are like rotten spots [contaminating the food] at your love feasts, while they gorge themselves without fear [i.e., unashamed of their selfish indulgence]. [Note: This passage may mean "like selfish shepherds, looking out only for themselves, they eat the grain set out for the animals"]. They are like clouds that blow over without producing rain; [they are like] trees in the fall that do not produce any fruit and have been uprooted, [thus] being dead twice [i.e., fruitless and rootless].
