For a meaning of the name Adonikam is "My
Lord Has Risen."
There's only one man named Adonikam in the Bible, although he plays no role in it. His family is reported by
both Ezra to be among the first wave to returned from exile, who counts 666
The number of this clan of people returning from the first diaspora after seventy years in Babylon is the only other place
in scripture where we find this strange reference to 666.
Is interesting to some people that the name of the man referred to in that case means: "My Lord
Has Risen." This certainly seems to fit well for those Jews incarcerated and detained in the death camps just at the
advent of what would be there return to the Holy Land.
What is unique in both cases is that the Jews returned to Israel after a long spell of exile. The
metaphor may be intended in that, after Hitler fell, Israel became a state again. That was identical to the situation when
the Jews returned from the captivity in the day of Daniel, for this one man and his people, mentioned for no other reason
Alfred Jones (Dictionary of Old Testament Proper Names)
goes with the derivation (qim), meaning adversary, and reads rather oddly Lord Of Enemies.
This too seems appropriate to Rev 13 and the appellation of the number to Hitler,
certainly the Lord of the Jewish enemy.
