What about Abraham having sex with Sarah's Egyptian maid servant Hagar, because Jehovah said he was going to have another son? I guess this would be a little different, but not much. If a couple wanted to have a child, would the surrogate be sinning by having the insemination or just the old in and out? One drawback might be that the offspring starts another religion, which could put a kink in things...what was Abraham thinking?
Sincerely,
