Short Answer: The identity of the “certain man” in is not explicitly revealed in the Bible. As for extra-biblical sources, there isn’t any historical or archaeological evidence I know of that provides additional information about this particular man. The early Christian writings such as the writings of the early Church Fathers or the Apocryphal Gospels, do not appear to mention him either. Even if they did it would be hard to associate it with a nameless man from the Bible.
Let's look at all the relevant verses from the Bible:
- Matthew 26:18 NKJV - And He said, “Go into the city to a certain man,
and say to him, ‘The Teacher says, “My time is at hand; I will keep
the Passover at your house with My disciples.” ’ ”
- Mark 14:13-14 NKJV - And He sent out two of His disciples and said to
them, “Go into the city, and a man will meet you carrying a pitcher
of water; follow him. 14 Wherever he goes in, say to the master of
the house, ‘The Teacher says, “Where is the guest room in which I may
eat the Passover with My disciples?” ’
- Luke 22:10-12 - And He said to them, “Behold, when you have entered
the city, a man will meet you carrying a pitcher of water; follow him
into the house which he enters. 11 Then you shall say to the master
of the house, ‘The Teacher says to you, “Where is the guest room
where I may eat the Passover with My disciples?” ’ 12 Then he will
show you a large, furnished upper room; there make ready.”
Matthew 26:18
- He’s a certain man, not necessarily a random one.
- He knew who “the Teacher” referred to.
- He had a house in the city of Jerusalem.
We can probably assume this house was large enough to accommodate Jesus and His disciples for the Passover meal.
This may infer that the man was well-off.
Mark 14:13-14
- He had a house in the city of Jerusalem.
- A man (likely a servant) from his house was carrying a pitcher of water.
- The disciples were to follow this man to the house.
- The owner of the house would understand who “the Teacher” was.
- His house has a guest room.
We can probably assume this room was large enough to accommodate Jesus and His disciples for the Passover meal.
This may infer that the man was well-off.
Luke 22:10-12
- Another man (likely a servant) from his house was carrying a pitcher of water.
- The owner of the house will understand who “the Teacher” is.
- The owner has a large upper room which is furnished and prepared.
We can probably assume this room was large enough to accommodate Jesus and His disciples for the Passover meal.
This may infer that the man was well-off given that he had a large, furnished upper room that could accommodate Jesus and His disciples for the Passover meal.
Ellicott's Commentary for English Readers says on Matthew 26:18:
To such a man.—The Greek word is that used when the writer knows, but
does not care to mention, the name of the man referred to. St. Mark
and St. Luke relate the sign that was given them. They were to meet a
man “bearing a pitcher of water” and follow him. and were to see in
the house into which he entered that in which they were to make their
preparations. The master of the house was probably a disciple, but
secretly, like many others, “for fear of the Jews” (John 12:42), and
this may explain the suppression of his name. He was, at any rate, one
who would acknowledge the authority of the Master in whose name the
disciples spoke.
Barnes' Notes on the Bible says on Matthew 26:18:
There can be little doubt that Jesus was acquainted with this man, and
that he was a disciple. The direction which he gave his disciples most
clearly proves that he was omniscient. Amid so great a multitude going
at that time into the city, it was impossible to know that "a
particular man would be met" - a man bearing a pitcher of water -
unless Jesus had all knowledge, and was therefore divine.
Gill's Exposition says on Matthew 26:18:
and say unto him; not to the man bearing the pitcher of water; but, as
the other Evangelists say, to the good man of the house, the owner of
it, who probably might be one of Christ's disciples secretly; for many
of the chief rulers in Jerusalem believed on Christ, though they did
not openly confess him, for fear of the Pharisees, as Nicodemus, and
Joseph of Arimathea; and this man might be one of them, or some other
man of note and wealth; since they were to find, as they did, a large
upper room furnished and prepared. For, it seems, that without
mentioning his name, the man would know him by their language...
