You started out claiming that Jonathan was David's yf. Now you are claiming Jonathan was older. But at the same time, you are claiming there was no sexual interest, which would mean they were not yf/af. Yet despite the lack of sexual attraction, you still call them lovers. Somehow, you throw King Saul into the mix. Then you toss in an inexplicable question about whether such a relationship could be sinful.

Sorry, but at this point, I have no idea what you are trying to say.
