Exodus 34:14, “(For you shall worship no other god, for the Lord, whose name is Jealous, is a jealous God).” ESV
“Israel is referred to as the Lord’s bride (Isaiah 54:5, 6; 62:5; Jeremiah 31:32). Idolatry was the spiritual equivalent of adultery (Jeremiah 3:8, 9, 20; Ezekiel 16:20-34; 23:37).” ESV Hebrew-Greek Key Word Study Bible Notes
Francine Rivers wrote a book called, “Redeeming Love.” In it, God told a husband he could not love or worship his wife more than God. The man said, “Lord, I do keep you first.” Then God pointed out that his wife was worshipping him and putting him before God.
God has to be first before everyone and everything.
