Military operation to surround a community. It was a common experience in the ancient world for towns to be surrounded by an enemy and all supplies cut off. The defenders built walls and gates to resist the enemy, and sometimes were successful. Samaria held out against the Assyrians for three years, until 722. The siege against Jerusalem in 701 was lifted and the city remained free until the Babylonian siege of 597 when Nebuchadnezzar attacked it (2 Kgs. 25: 1). Some of the Roman siege works against Masada are still visible.
