And am I to infer from your question that, because Cain received nothing in return, the payments qualify as "alms?"

That's right. What do you think alms are?

Blue Letter Bible

1) mercy, pity
a) esp. as exhibited in giving alms, charity
2) the benefaction itself, a donation to the poor, alms

There ya’ go! Cain should just announce a press conference and declare that he took pity on the woman, and saw himself as engaging in an act of charity. Problem solved.

Did not know of that website.

Thanks
