And went after the man of God, and found him sitting under an
oak
To shelter him from the heat, and being faint, hungry, and thirsty; so the ancients of old made use of oaks for a covering, before houses were invented F5; thus Abraham pitched his tent in the plain, or under the oak, of Mamre, ( Genesis 13:18 )
and he said unto him, art thou the man of God that camest from Judah?
which he might guess at from his habit, and from the description his sons had given of him:
and he said, I am;
owned himself to be the person he inquired after.
