1 Kings 13-15

Jeroboam was appointed by God to rule over most of Israel. This came about, he was told, because of Solomon's rejection of following God. When all of this came to pass you would think that Jeroboam would have served God all of his days; he didn't. He chose his own desires over God's. Even after the unnamed prophet spoke against his pagan altar, Jeroboam showed his distance from God by asking the prophet to pray to "your God". Apparently Jeroboam had completely abandoned the God who had made him king.
