‘ And Manoah rose up and went after his wife, and came to the man, and said to him, “Are you the man who spoke to the woman?” And he said, “I am.” '
When Manoah approached the man he asked him whether he was the man who had spoken to his wife. By this, of course, Manoah meant the Man who had given his wife the divine message that she had received. He wanted to know that this was the direct answer to his prayer to Yahweh. But he was not yet aware that this was the Angel of Yahweh Himself. The angel replied positively.
