Jesus spoke in parables. "Another parable put he forth unto them, saying, The kingdom of heaven is likened unto a man which sowed good seed in his field: but while men slept, his enemy came and sowed tares among the wheat, and went his way. But when the blade was sprung up, and brought forth fruit, then appeared the tares also. So the servants of the householder came and said unto him, Sir, didst not thou sow good seed in this field? from whence then hath it tares? He saith unto them, An enemy hath done this. The servants said unto him, Wilt thou then that we go and gather them up? But he said, Nay: lest while ye gather up the tares, ye root up also the wheat with them. Let both grow together until the harvest: and in the time of harvest I will say to the reapers, Gather ye together first the tares, and bind them into bundles to burn them: but gather the wheat into my barn. John 13:24-30. John 13:34-43 continues, “All these things spake Jesus unto the multitude in parables; and without a parable spake he not unto them; that it might be fulfilled which was spoken by the prophet, saying, I will open my mouth in parables; I will utter things which have been kept secret from the foundation of the world. Then Jesus sent the multitude away, and went into the house: and his disciples came unto him, saying, Declare unto us this parable of the tares of the field. He answered and said unto them, He that soweth the good seed is the Son of man: the field is the world: the good seed are the children of the kingdom; but the tares are the children of the wicked one: the enemy that sowed them is the devil: the harvest is the end of the world; and the reapers are the angels. As therefore the tares are gathereed and burned in the fire; so shall it be in the end of the world. The Son of man shall send forth his angels, and they shall gather out of his kingdom all things that offend, and them which do iniquity; and shall cast them into a furnace of fire: there shall be wailing and gnashing of teeth. Then shall the righteous shine forth as the sun in the kingdom of thier Father. Who hath ears to hear, let him hear.”
When Jesus told Peter, "if I will that he tarry till I come, what is that to thee? Follow thou me. Then went this saying abroad among the brethren, that that disciple should not die: yet Jesus said not unto him, He shall not die; but, If I will that he tarry till I come, what is that to thee? John 21:22-23.
In John 21:20 it talks about "the disciple whom Jesus loved, following; which also leaned on his breast at supper and said, Lord, which is he that betrayeth thee?
John 13:23 says, "Now there was leaning on Jesus’ bosom one of his disciples, whom Jesus loved.
What is the name of that disciple? He tells us himself in John 21:24, “This is the disciple which testifieth of these things…”
