Israel had a rich history of a unique relationship with God. There were the conversations between God and many of the nations leaders; events like Abraham’s conversation with the Lord at the entrance to his tent and Moses covering his face after face-to-face conversations with God. There were the recorded miracles dear to every Israelite, such as the Red Sea crossing and Elijah calling fire from heaven to ignite his sacrifice. Prophets spoke the word of the Lord, and the nation heard!
Until there was nothing more to hear.
