Parallel
2 Chronicles 36:13
Brenton's English Septuagint · Berean Standard Bible
in that he rebelled against king Nabuchodonosor, which he adjured him by God [not to do]: but he stiffened his neck, and hardened his heart, so as not to return to the Lord God of Israel.
He also rebelled against King Nebuchadnezzar, who had made him swear by God. But Zedekiah stiffened his neck and hardened (note: Or made strong or made courageous) his heart against turning to the LORD, the God of Israel.
