Now I tell you before it come, that, when it is come to pass, ye may believe that I am he.
Context
18 I don’t speak concerning all of you. I know whom I have chosen; but that the Scripture may be fulfilled, ‘He who eats bread with me has lifted up his heel against me.’
19 From now on, I tell you before it happens, that when it happens, you may believe that I am he.
20 Most certainly I tell you, he who receives whomever I send, receives me; and he who receives me, receives him who sent me.”
