'Someone' in the Bible

Who is someone who desires life, and loves many days, that he may see good?

When someone comes to visit, he pretends to be friendly; he thinks of ways to defame me, and when he leaves he slanders me.

Don't be afraid when someone gets rich, when the glory of his household increases.

For it is not an enemy who insults me I could have handled that nor is it someone who hates me and who now arises against me I could have hidden myself from him

May they flow away like rain water that runs off, may they become like someone who shoots broken arrows.

How long will you rage against someone? Would you attack him as if he were a leaning wall or a tottering fence?
