Genesis 14:14

14When Abram had heard this, namely, that his brother Lot had been taken captive, he numbered three hundred and eighteen of his own armed men and he went in pursuit all the way to Dan.
14:14These 318 were not servants, but a group of armed men who worked for Abram, guarding his possessions and his servants. There were no police in those days, and someone with a very large contingent of servants and a very large family needed armed men to protect them. These men are analogous to a large corporation having its own security guards. Also, it was brave and daring for such a small and lightly armed group, without experience in warfare, to actually attack a large army deployed in the field.(Conte)
