13 But you have followed the ways of the kings of Israel, and you have led Judah and the people of Jerusalem to prostitute themselves, just as the house of Ahab did. You have also murdered your own brothers, members of your own family, men who were better than you.

but have walked in the way of the kings of Israel and have enticed Judah and the inhabitants of Jerusalem into whoredom, as the house of Ahab led Israel into whoredom, and also you have killed your brothers, of your father's house, who were better than yourself,
Instead, you have been as evil as the kings of Israel. You have led the people of Jerusalem and Judah to worship idols, just as King Ahab did in Israel. And you have even killed your own brothers, men who were better than you.
