2 Chronicles 20:2-4 NIV
Some people came and told Jehoshaphat, “A vast army is coming against you from Edom, from the other side of the Dead Sea. It is already in Hazezon Tamar” (that is, En Gedi). Alarmed, Jehoshaphat resolved to inquire of the LORD, and he proclaimed a fast for all Judah. The people of Judah came together to seek help from the LORD; indeed, they came from every town in Judah to seek him.
