Judges 13 · a question people ask
Isaiah names a child "Wonderful Counselor" (Isaiah 9:6). Is that the angel's name here?
In the WEB the angel says, "Why do you ask about my name, since it is incomprehensible?" (13:18). In Hebrew his word is pil'i (Strong's H6383), which Brown-Driver-Briggs gives as "wonderful, incomprehensible". Isaiah's "His name will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace" (Isaiah 9:6) has a different word, pele' (Strong's H6382), which Brown-Driver-Briggs gives as "wonder". Strong's derives both from the verb pala', the verb of "did an amazing thing" in 13:19. So the two are related words, not the same word, and neither passage cites the other. This chapter keeps to what the angel said: he didn't give his name.
The verses
“Manoah said to the LORD’s angel, “What is your name, that when your words happen, we may honor you?” The LORD’s angel said to him, “Why do you ask about my name, since it is incomprehensible?” So Manoah took the young goat with the meal offering, and offered it on the rock to the LORD. Then the angel did an amazing thing as Manoah and his wife watched.”
“For a child is born to us. A son is given to us; and the government will be on his shoulders. His name will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace.”
