Manoah said to the angel of Yahweh, I pray you, let us detain you, that we may make ready a kid for you.
This chapter appears as one of the most significant in the entire O.T., because of what is said here of the Angel of Jehovah.  Back in  Judges 13:11, when Manoah asked if "the man" was the same one who had earlier appeared to his wife, the answer was, "I AM."  These very words were often used by Jesus Christ himself as his identification, as in  John 8:58;  Mark 14:62;  John 18:5, etc.  This strongly supports the belief that the Angel of Jehovah was none other than the pre-incarnate Son of God.
