🔼The name Ziz in the Bible
The name Ziz occurs only once in the Bible. When a battle between Israel under king Jehoshaphat and the Moabites, Ammonites and some of the Meunites was about to begin, the Spirit of YHWH came upon Jahaziel, son of Zechariah, who said that the battle was the Lord's and not theirs. The day after, the enemy would come up by the ascent of Ziz, and Israel would confront them at the end of the valley in front of the wilderness of Jeruel (2 Chronicles 20:16), and just stand there.
The next day, Israel's army was spearheaded by singers and praisers, who sang and worshipped while below them the Ammonites and Moabites rose up against the men of Seir and destroyed them and each other (20:23). Word of this marvel spread about the surrounding nations, and the kingdom of Jehoshaphat remained at peace since then.
