HaShem is a jealous Elohim (Exodus 34:14). Isra’el is His wife and He is a jealous Husband (Isaiah 54:5, Jeremiah 3:20-21). In order to show Isra’el that He expected her to be faithful, He used a familiar cultural practice to demonstrate how He would decide Isra’el’s unfaithfulness and its consequences if she aroused His jealousy.
