To my knowledge Jesus never used the word "tokos." Jesus most likely spoke Aramaic and the words which are used in the Gospels are merely Greek translations of the Hebraic words he spoke. Trust me on this one, admit that you didn't have full knowledge of what you were talking about and back out gracefully. You'll gain more respect and a better audience for relevant points you wish to make in the future. (I assume you did follow the link and yet chose to ignore it. Why you did so I have no idea.)
When in doubt you go to the videotape -- You say you trust the Word of God -- and you know what it means -- prove it from the only source that counts -- an absolute source
Did Jesus use the word "tokos" to mean "interest, usury" or not?. Did he ever use it anyother time to mean anything else? Answer the questions --- they are not hard. But if you don't know what you are talking about -- then sit down and quit taking up cyberspace.
Be ready to have folks say that "unless you have proof that Jesus spoke it Aramaic, you can't make the claim that he did speak in Aramaic". It's coming.
