15 and he saith, 'Attend, all Judah, and ye inhabitants of Jerusalem, and O king Jehoshaphat, Thus said Jehovah to you, Ye fear not, nor are afraid of the face of this great multitude, for not for you 'is' the battle, but for God. 16 To-morrow, go ye down against them, lo, they are coming up by the ascent of Ziz, and ye have found them in the end of the valley, the front of the wilderness of Jeruel. 17 Not for you to fight in this; station yourselves, stand, and see the salvation of Jehovah with you, O Judah and Jerusalem—be not afraid nor fear ye—to-morrow go out before them, and Jehovah 'is' with you.'
Matthew Henry's Commentary on 2 Chronicles 20:15-17
Commentary on 2 Chronicles 20:14-19
(Read 2 Chronicles 20:14-19)
The Spirit of prophecy came upon a Levite in the midst of the congregation. The Spirit, like the wind, blows where and on whom He listeth. He encouraged them to trust in God. Let the Christian soldier go out against his spiritual enemies, and the God of peace will make him more than a conqueror. Our trials will prove our gain. The advantage will be all our own, but the whole glory must be given to God.
