You kind of missed the whole point of where the term 'good Samaritan' came from. The info you gave on who the Samaritans were is great but you didn't put in the parable Jesus told:
Luke 10:29 But he, willing to justify himself, said unto Jesus, And who is my neighbour? 30 And Jesus answering said, A certain man went down from Jerusalem to Jericho, and fell among thieves, which stripped him of his raiment, and wounded him, and departed, leaving him half dead. 31 And by chance there came down a certain priest that way: and when he saw him, he passed by on the other side. 32 And likewise a Levite, when he was at the place, came and looked on him, and passed by on the other side. 33 But a certain Samaritan, as he journeyed, came where he was: and when he saw him, he had compassion on him, 34 and went to him, and bound up his wounds, pouring in oil and wine, and set him on his own beast, and brought him to an inn, and took care of him. 35 And on the morrow when he departed, he took out two pence, and gave them to the host, and said unto him, Take care of him; and whatsoever thou spendest more, when I come again, I will repay thee. 36 Which now of these three, thinkest thou, was neighbour unto him that fell among the thieves? 37 And he said, He that shewed mercy on him. Then said Jesus unto him, Go, and do thou likewise.
The priests and Levites were the ones who were SUPPOSED to look after the poor and needy in Israel but the Samaritans were under no such obligation. Yet, in the story, it was a Samaritan who did what the priest and the Levite neglected to do.
I think a lot of people continue to misinterpret 2 Peter 3:8. I don't think this is meant to refer to any specific time. It's just an illustration that God is OUTSIDE of time and that He doesn't measure time the way we do. Days and years mean nothing to Him in the context of eternity.
That being said, you did make an interesting observation and I suppose it's not outside the realm of possibility. I wouldn't try to go and make a doctrine out of it, though.
