Genesis 27:18

He went to his father and said, “My father!” Isaac ¹  replied, “Here I am. Which are you, my son?” ² 

He went to his father and said, "My father." "Yes, my son," he answered. "Who is it?"

Then he came to his father and said, "My father." And he said, "Here I am. Who are you, my son?"

Jacob carried the platter of food to his father and said, "My father?" "Yes, my son," he answered. "Who is it––Esau or Jacob?"

He went to his father and said, "My father!" "Yes?" he said. "Which son are you?"

And he came to his father, and said, My father: and he said, Here am I: who are you, my son?

So he went in to his father, and said, "My father"; and he said, "Here I am; who are you, my son?"

So he went to his father and said, "My father." And he said, "Here I am. Who are you, my son?"

He went to his father and said, “My father!” Isaac ¹  replied, “Here I am. Which are you, my son?” ² 

¹ tn Heb “and he said”; the referent (Isaac) has been specified in the translation for clarity.

² sn Which are you, my son? Isaac’s first question shows that the deception is going to require more subterfuge than Rebekah had anticipated. Jacob will have to pull off the deceit.
