'War' in the Bible

In the days of King Saul they made war with the Hagrites, who fell by their hands; and they lived in their tents throughout all the land east of Gilead.

The sons of Reuben, the Gadites, and the half-tribe of Manasseh—valiant men able to bear shield and sword, and to shoot with the bow, and skillful in war—were 44,760 who went to war.

And these Israelites, [on the east side of the Jordan River] made war with the Hagrites [a tribe of northern Arabia], Jetur, Naphish, and Nodab.

With them by their generations according to their fathers’ households were 36,000 troops of the army for war, for they had many wives and children.

All these were the sons of Jediael, according to the heads of their fathers’ households, 17,200 courageous men of valor, fit for military service.

All these were sons (descendants) of Asher, heads of their fathers’ houses, choice men, courageous men, chiefs of the leaders. Their number, enrolled by genealogies for service in war, was 26,000 men.

These are the ones who came to David at Ziklag, while he still concealed himself from Saul the son of Kish; they were among the courageous men who helped him in battle.

Courageous men from the Gadites came over to David in the stronghold in the wilderness, men trained for war, who could handle shield and spear, whose faces were like the faces of lions, and who were swift as gazelles on the mountains.

Those of the tribe of Judah who carried shield and spear were 6,800, armed for war;

of the tribe of Zebulun, there were 50,000 in military service who could draw up in battle formation with all kinds of weapons of war and helped David, men with an undivided heart.

From the other side [east] of the Jordan River, of [the tribes of] Reuben and Gad and the half-tribe of Manasseh, 120,000 men, armed with all kinds of weapons of war for the battle.

All these, being men of war arrayed in battle formation, came to Hebron with a perfect (committed) heart to make David king over all Israel; and all the rest of Israel were also of one mind to make David king.

Now it came about after this that war broke out at Gezer with the Philistines; then Sibbecai the Hushathite killed Sippai, one of the descendants of the giants, and they were subdued.

There was war again with the Philistines, and Elhanan the son of Jair killed Lahmi the brother of Goliath the Gittite, the shaft of whose spear was like a weaver’s beam.

Again there was war at Gath, where there was a man of great stature who had twenty-four fingers and toes, six fingers on each hand and six toes on each foot; and he also was descended from the giants.

But God said to me, ‘You shall not build a house for My Name (Presence), because you are a man of war and have shed blood.’
