Israel Has Once Worshiped Baal

https://shereadstruth.com/israel-worships-baal/ It says here that Israel once worshiped Baal and God punished them by killing 10s of 1000s of people. Yet I could not find any bible for Baal and we need to find this book, since there has to be one, in my humblest. The book should come from at most the Canaanites. May God bless!
