'War' in the Bible

a time to love, and a time to hate; a time for war, and a time for peace.

Just as no human being has control over the wind to restrain it, so also no human being has control over the day of his death. Just as no one is discharged during war, so wickedness will not release those who practice it.

Wisdom is better than weapons of war, and a single sinner can destroy a lot of good.
