John 13:20-21, 38

I assure you and most solemnly say to you, the one who receives and welcomes whomever I send receives Me; and the one who receives Me receives Him who sent Me [in that same way].” After Jesus had said these things, He was troubled in spirit, and testified and said, “I assure you and most solemnly say to you, one of you will betray Me and hand Me over.”

Jesus answered,“Will you [really] lay down your life for Me? I assure you and most solemnly say to you, before a rooster crows you will deny and completely disown Me three times.
