Luke 19:5
When Jesus reached the spot, he looked up and said to him, Zacchaeus, come down immediately. I must stay at your house today — looked up: Jesus saw the man in the tree before the man had any means of introducing himself. Zacchaeus — the personal address communicates that Jesus knew him. Come down immediately; I must stay at your house today: the initiative is entirely Jesus'. I must (dei) stay: the divine necessity of the encounter.
