KJV(i)
16 And the angel of the LORD said unto Manoah, Though thou detain me, I will not eat of thy bread: and if thou wilt offer a burnt offering, thou must offer it unto the LORD. For Manoah knew not that he was an angel of the LORD.
17 And Manoah said unto the angel of the LORD, What is thy name, that when thy sayings come to pass we may do thee honor?
18 And the angel of the LORD said unto him, Why askest thou thus after my name, seeing it is secret?
