And he divided himself against them, he and his servants, by night, and smote them, and pursued them unto Hobah, which is on the left hand of Damascus.
Genesis 14:15

Abraham had 318 trained soldiers in his household when Chedorlaomer raided Sodom. He was practically a nation already, but this was hardly a great army. Yet, he defeated the united force of multiple kings who had just defeated three groups of giants. If Chedorlaomer was a Titan, what does that make Abraham? A servant of YHWH.
