'War' in the Bible

A time to love, and a time to hate; a time of war, and a time of peace.

There is no man that hath power over the spirit to retain the spirit; neither hath he power in the day of death: and there is no discharge in that war; neither shall wickedness deliver those that are given to it.

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 weapons of war: but one sinner destroyeth much good.
