One of the Philistine warriors was Ishbibenob, who was a descendant of the Rephaim, and he tried to kill David. Ishbibenob was armed with a new sword, and his bronze spearhead alone weighed about three and a half kilogrammes.
The Philistines heard that David was now king of Israel, and they came into the hill country to try and capture him. But David found out and went into his fortress.
Some time later, Israel fought a battle against the Philistines at Gezer. During this battle, Sibbecai from Hushah killed Sippai, a descendant of the Rephaim, and the Philistines were defeated.
