2 Chronicles 20:15

15 He said, "Attention everyone - all of you from out of town, all you from Jerusalem, and you King Jehoshaphat - God's word: Don't be afraid; don't pay any mind to this vandal horde. This is God's war, not yours.

2 Chronicles 20:15 Meaning and Commentary

2 Chronicles 20:15

And he said, hearken ye, all Judah, and ye inhabitants of
Jerusalem, and thou King Jehoshaphat
There is a climax or gradation in these words rising from the lowest to the highest; from the people of the cities in the country, to the inhabitants of Jerusalem the metropolis, and from thence to the king the supreme governor: thus saith the Lord unto you, be not afraid, nor dismayed, by reason of
this great multitude;
whose numbers were discouraging to the king, and he had taken notice of them, which this respects: for the battle is not your's, but God's:
the cause was his, and he would espouse and maintain it; not they, but he, would fight the battle, and therefore they had nothing to fear.

2 Chronicles 20:15 In-Context

13 Everyone in Judah was there - little children, wives, sons - all present and attentive to God.

14 Then Jahaziel was moved by the Spirit of God to speak from the midst of the congregation. (Jahaziel was the son of Zechariah, the son of Benaiah, the son of Jeiel, the son of Mattaniah the Levite of the Asaph clan.)

15 He said, "Attention everyone - all of you from out of town, all you from Jerusalem, and you King Jehoshaphat - God's word: Don't be afraid; don't pay any mind to this vandal horde. This is God's war, not yours.

16 Tomorrow you'll go after them; see, they're already on their way up the slopes of Ziz; you'll meet them at the end of the ravine near the wilderness of Jeruel.

17 You won't have to lift a hand in this battle; just stand firm, Judah and Jerusalem, and watch God's saving work for you take shape. Don't be afraid, don't waver. March out boldly tomorrow - God is with you."
