The Freemasons. I used to live with someone who was part of the frat'. I picked up on an ociated word.?

I genuinely, TOTALLY and playfully dropped it into a conversation with my MD toda (I didn't know he was a Freemason) He automatically appeared stunned and said "Eh?.. wait a minute.... that's just a Biblical word.... but how do you know about that?" He then went on to ask if I was a Freemason. It transpires that he himself is. Now,.... here's the interesting part. I was in a certain part of town this evening and he called me up and asked me for a drink. he said he happened to be there as well. We sat for an hour. Was I getting checked out, and if so what would the signs have been.
