Everything is God’s. Every tangible and intangible thing.
He is jealous in all the right ways if things are done without this consideration. Things like non-thankfulness, absence of praise, independence (from God not people), half-hearted trust, an uncaring spirit, self aggrandizement, trivial pursuits for the sake of ignoring significant pursuits, almost-significant pursuits that we throw ourselves into, downright terrible pursuits… and mopey boredom (a.k.a. not doing anything about anything because nothing is worth your effort).
