Lottery donation

I received a text from 2 different numbers saying that they won the lottery and wanted to donate to some people. One said they wanted to give me $300,000, and the other one said they wanted to give me $800,000. They wanted my name and address as also a picture. I told them that I wasn't comfortable doing that and was this a scam? They went religious on me and said it was legitimate and a blessing they wanted me to have. The reason they gave for the picture was to make sure they didn't donate twice to any one person. What do you think Scam??
