Genesis 27:18

And he came unto his father,.... Into the tent and apartment where he was:

and said, my father; to try whether he was awake, and to let him know that he was come, since he could not see him:

and he said, here [am] I; what hast thou to say to me?

who [art] thou, my son? for, from the voice and the quick dispatch made, he suspected it was not his son Esau.
