'War' in the Bible

A time for love and a time for hate; a time for war and a time for peace.

No man has authority over the wind, to keep the wind; or is ruler over the day of his death. In war no man's time is free, and evil will not keep the sinner safe.

And again I saw under the sun that the reward goes not to him who is quick, or the fruits of war to the strong; and there is no bread for the wise, or wealth for men of learning, or respect for those who have knowledge; but time and chance come to all.

There was a little town and the number of its men was small, and there came a great king against it and made an attack on it, building works of war round about it.

Wisdom is better than instruments of war, but one sinner is the destruction of much good.
