Jeremiah 38:10

Zedekiah authorized Ebed-melech to use 30 of the eunuch’s own men to extract Jeremiah from the cistern. [Note: The Septuagint and one ancient Hebrew manuscript have "three" instead of "30," but 30 is probably correct.] Evidently Zedekiah expected that Ebed-melech might encounter some opposition and would need a lot of manpower.
