But if thou wilt go, do it, be strong for the battle: God shall make thee fall before the enemy: for God hath power to help, and to cast down.

But if thou wilt go, do valiantly , be strong for the battle: God will cast thee down before the enemy; for God hath power to help, and to cast down.

And if thou think that battles consist in the strength of the army, God will make thee to be overcome by the enemies: for it belongeth to God both to help, and to put to flight.

but if thou art going, do it, be strong for battle, God doth cause thee to stumble before an enemy, for there is power in God to help, and to cause to stumble.'

But if you will go, do it; be strong for the battle: God shall make you fall before the enemy: for God has power to help, and to cast down.

But go yourself, and be strong in war; God will not let you go down before those who are fighting against you; for God has power to give help or to send you down before your attackers.

But if thou wilt go, and do engage never so valiantly in battle, God will cast thee down before the enemy; for God hath power to help, and to cast down.'

But if you think that a war stands by the strength of the army, God will cause you to be overwhelmed by the enemies. For indeed, it belongs to God to assist, and to put to flight."

If the present text is regarded as sound, this passage must be taken ironically. But most recent commentators supply a second negative, and render it: "But go thou alone, act, be strong for the battle - God shall then not make thee to fall."

But (f) if thou wilt go, do [it], be strong for the battle: God shall make thee fall before the enemy: for God hath power to help, and to cast down.
(f) If you will not give credit to my words.

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", &c.
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.

Amaziah is to go alone, and show himself valiant in war, and the Lord will help him to conquer. This is without doubt the thought in 2-Chronicles 25:8, which, however, does not seem to be contained in the traditional Masoretic text. האל יכשׁילך can hardly, after the preceding imperatives - do, be strong for battle - be otherwise translated than by, "and God will cause thee to stumble before the enemy." But this is quite unsuitable. Clericus, therefore, would take the words ironically: sin minus, tu vadito, etc.; i.e., if thou dost not follow my advice, and takest the Israelites with thee to the war, go, show thyself strong for the war, God will soon cause thee to stumble. But אם כּי can never signify sin minus. Others, as Schmidt and Ramb., translate: Rather do thou go alone (without the Israelitish auxiliaries), and be valiant, alioquin enim, si illos tecum duxeris, corruere te faciet Deus; or, May God make thee fall before the enemy (De Wette). But the supplying of alioquin, which is only hidden by De Wette's translation, cannot be grammatically justified. This interpretation of the יכשׁילך would be possible only if the negation לא אם כּי stood in the preceding clause and יכשׁילך was joined to it by ו. The traditional text is clearly erroneous, and we must, with Ewald and Berth., supply a לא or ולא before יכשׁילך: God thou (alone), do, be valiant for battle, and God will not let thee come to ruin.
(Note: Even the old translators could make nothing of the present text, and expressed the first clause of the verse as they thought best. lxx, ὅτι ἐὰν ὑπολάβης κατασχῦσαι ἐν τούτοις; Vulg., quod si putes in robore exercitus bella consistere; after which Luth., "denn so du komest das du eine knheit beweisest im streit, wird Gott dich fallen lassen fr deinen Feinden.")
After this we have very fittingly the reason assigned: "for with God there is power to help, and to cause to fall."

Do it - It is an ironical concession like that, go, and prosper.
