חֵיל Strong’s #2426 hheyl

Peace be within thy walls, And prosperity within thy palaces.

Psalm 122:7


Many of the cities mentioned in the Bible were surrounded by a large wall to keep an enemy from entering the city. Because an army performs this same protective function, they are also called a “wall,” or in Hebrew a hheyl. Hhayil (a closely related word) is the Modern Hebrew word for the “army” of Israel.
