'War' in the Bible

He trains my hands for war,So that my arms can bend a bow of bronze.

Though an army encamp against me,My heart will not fear;Though war arise against me,Even in this I am confident.

The words of his mouth were smoother than butter,But his heart was hostile;His words were softer than oil,Yet they were drawn swords.

Rebuke the beasts [living] among the reeds [in Egypt],The herd of bulls (the leaders) with the calves of the peoples;Trampling underfoot the pieces of silver;He has scattered the peoples who delight in war.

There He broke the flaming arrows,The shield, the sword, and the weapons of war. Selah.

The fire [of war] devoured His young men,And His [bereaved] virgins had no wedding songs.

I am for peace, but when I speak,They are for war.

Blessed be the Lord, my Rock and my great strength,Who trains my hands for warAnd my fingers for battle;
