John 13:21 WEB

¹⁹  From now on, I tell you before it happens, that when it happens, you may believe that I AM.

²⁰  Most assuredly I tell you, he who receives whomever I send, receives me; and he who receives me, receives him who sent me.'

²¹  When Jesus had said this, he was troubled in spirit, and testified, 'Most assuredly I tell you that one of you will betray me.'

²²  The disciples looked at one another, perplexed about whom he spoke.

²³  One of his disciples, whom Jesus loved, was at the table, leaning against Jesus' breast.
