Jeremiah 39:3-4

3Then all the officials of the king of Babylon came in and sat in the Middle Gate [establishing both military control of the city and their authority to judge the captives]: Nergal-sar-ezer, Samgar-nebu, Sar-sekim the Rab-saris (chief of the eunuchs), and Nergal-sar-ezer the Rab-mag (chief of the magicians), with all the rest of the officials of the king of Babylon.

4When Zedekiah the king of Judah and all the men of war saw them, they fled and escaped from the city at night by way of the king’s garden, through the gate between the two walls; and the king went out toward the Arabah (Jordan Valley).
