Parallel
2 Chronicles 12:1
Jewish Publication Society 1917 · Berean Standard Bible
And it came to pass, when the kingdom of Rehoboam was established, and he was strong, that he forsook the law of the LORD, and all Israel with him.
After Rehoboam had established his sovereignty and royal power, he and all Israel (note: That is, Judah; in 2 Chronicles, Judah is occasionally called Israel, as representative of the true Israel.) with him forsook the Law of the LORD.
