Chronicles II 25:8 Meaning and Commentary

2 Chronicles 25:8

But if thou wilt go, do it, be strong for the battle
An ironical expression; if thou wilt not be advised, take them with thee, and try what thou canst do; exert all thy courage, and use thy military skill, and mark the issue:

God shall make thee fall before the enemy;
notwithstanding the number of thy troops, and those of thy auxiliaries; though some take them to be spoken seriously, and read the words, "but go thou"; that is, alone, without the hired troops, and fight boldly and courageously; or otherwise "God shall make thee fall"

for God hath power to help and to cast down;
to help with a few, and to cast down with many; to help without the hired Israelites, and to cast down with them.

Chronicles II 25:8 In-Context

6 Also he hired of Israel a hundred thousand mighty a hundred talents of silver.
7 And there came a man of God to him, saying, O king, let not the host of Israel go with thee; for the Lord is not with Israel, all the sons of Ephraim.
8 For if thou shalt undertake to strengthen with these, then the lord shall put thee to flight before the enemies: for it is of the Lord both to strengthen and to put to flight.
9 And Amasias said to the man of God, But what shall I do the hundred talents which I have given to the army of Israel? And the man of God said, The Lord can give thee much more than these.
10 And Amasias separated from the army that came to him from Ephraim, that they might go away to their place; and they were very angry with Juda, and they returned to their place with great wrath.
