'Forgive' in the Bible

Perhaps there are 50 righteous ones within the city. Will you actually destroy it and not forgive the place for the sake of the 50 righteous that are found there?

The LORD said, "If I find 50 righteous people within Sodom, I'll forgive the whole place for their sake."

You are also to say, ‘Look, your servant Jacob is right behind us.’” For he thought, “I want to appease Esau with the gift that is going ahead of me. After that, I can face him, and perhaps he will forgive me.”

So shall ye say unto Joseph, Forgive, I pray thee now, the trespass of thy brethren, and their sin; for they did unto thee evil: and now, we pray thee, forgive the trespass of the servants of the God of thy father. And Joseph wept when they spake unto him.
