John 10:1, 8

“I assure you and most solemnly say to you, he who does not enter by the door into the sheepfold, but climbs up from some other place [on the stone wall], that one is a thief and a robber.

All who came before Me [as false messiahs and self-appointed leaders] are thieves and robbers, but the [true] sheep did not hear them.
