Deuteronomy 23:9 - Matthew Poole's English Annotations on the Holy Bible

Then especially take heed, because that is a time and state of confusion and licentiousness, when, as one said, the laws of God and man cannot be heard for the noise of arms; and because the success of thy arms and enterprises depends upon God's blessing, which wicked men have no reason to expect; and because thou dost then carry thy life in thy hand, and therefore hast need to be well prepared for death and judgment.
