What it means
God is holy, and His holiness is not safe to trifle with. His jealousy is the loyalty of a husband, not the envy of a rival: He will not share you with idols because He is wholly yours.
Moses warns Israel against making any image to worship. Hebrews 12:29 quotes the line to a church that had grown casual.
Where it addresses you
Something has quietly taken His place in your life.
You have begun to treat Him as small.
