Exodus 34:14 - Matthew Poole's English Annotations on the Holy Bible

Whose name is Jealous; who hath made himself known by, and glories in that name, The jealous God, who cannot endure any competitor or corrival; whereas the false and puny gods of the heathens were contented with multitudes of partners. So this is properly said to be the name of God, whereby he is known and distinguished from all other gods.
