Bullinger has it...
Luk 17:21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is among you yourselves."
Bullinger's notes:
within = in the midst of, or, among: i.e. already there in the Person of the King (whose presence marks a kingdom). Greek entos, the same meaning as Greek. en (App-104.), with the plural rendered "among" 115 times in N.T. The same meaning as in Mat_12:28. Joh_1:26.
The Diaglott has it...
Luke 17:21 nor will they say: Lo here, or, or there; lo for, the majesty of the God in the midst of
you is.
