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.
