'External' in the Bible

From the descendants of Izhar, Chenaniah and his sons were assigned as officers and judges with responsibilities relating to external duties.

Hezekiah took courage and rebuilt all of the walls that had been broken down. Then he erected watch towers on them, and added another external wall. He fortified the terrace ramparts in the City of David and prepared a large number of weapons and shields.

Shabbethai and Jozabad, leaders of the Levites, were in charge of the external work for the temple of God;

And the effect of righteousness will be peace,And the result of righteousness will be quietness and confident trust forever.

Just as ritual circumcision cuts away the foreskin as an external symbol of dedicated covenant commitment, you must genuinely dedicate yourselves to the Lord and get rid of everything that hinders your commitment to me, people of Judah and inhabitants of Jerusalem. If you do not, my anger will blaze up like a flaming fire against you that no one will be able to extinguish. That will happen because of the evil you have done."
