'Four' in the Bible
The Philistines drew up in battle array to meet Israel. When the battle spread, Israel was defeated before the Philistines who killed about four thousand men on the battlefield.
Everyone who was in distress, and everyone who was in debt, and everyone who was discontented gathered to him; and he became captain over them. Now there were about four hundred men with him.
David said to his men, “Each of you gird on his sword.” So each man girded on his sword. And David also girded on his sword, and about four hundred men went up behind David while two hundred stayed with the baggage.
The number of days that David lived in the country of the Philistines was a year and four months.
But David pursued, he and four hundred men, for two hundred who were too exhausted to cross the brook Besor remained behind.
David slaughtered them from the twilight until the evening of the next day; and not a man of them escaped, except four hundred young men who rode on camels and fled.
