Hence we find in the 20th Chapter of Exodus, that after having forbidden His people to adore strange gods, He adds these words: "I am the Lord, thy God, mighty, jealous, visiting the iniquity of the fathers upon their children unto the third and fourth generation of those who hate Me."
And in Chapter 34 we read: "Adore not any strange god. The Lord His name is Jealous; He is a Jealous God." Second. He takes the name of the Jealous God, because He pursues with indignation and is intent upon removing whatever hinders the salvation of souls whom He loves as His spouses and His daughters and whose salvation He sovereignly desires. Third. Because as a Jealous Spouse, He is indignant against souls consecrated to His service if they love anything outside of Himself and for any other reason than for Him; or if they delight in things of the world and do not apply themselves to please Him in everything.
