When two disciples invite a mysterious stranger they met on the road to join them for the evening meal, they unwittingly invite the king to their table.
In keeping with biblical models of hospitality, the two disciples begged of the stranger, “Stay with us, for it is getting toward evening, and the day is now nearly over” (Luke 24:29). In this case, they were not merely fulfilling their obligation to show hospitality to strangers. The stranger had lit their hearts on fire, and they wanted to hear more from Him. They could not bear the thought of breaking off from Him.
The stranger agreed to stay with them, and the two disciples prepared a meal. Although they had already left Jerusalem, only two days of the festival of Passover had elapsed. They set matzah (unleavened bread) on the table and reclined with the stranger.
The stranger took the matzah bread in hand, lifted His eyes toward heaven according to His unique custom, and made the blessing, just as the disciples had heard Him often do. At every meal on every day that they had been with Him, they had heard Him chant the same words with the same intonations and seen Him make the same motions. They had seen that same beatific look of recognition in His eyes as He raised His gaze to the heavens above. Before the word “Amen” could even leave their lips, their eyes were opened, and they recognized Him. The stranger took a piece of the matzah into His mouth and vanished from the table. They stood up and looked around, but they did not see him. (Click to Source)
