Then Horam king of Gezer came up to help Lachish
Perhaps the rather induced to it, because it had no king to defend it. In Jerom's F5 time it was a village called Gazera, four miles from Nicopolis, or Emmaus, to the north: if this king came before the city was taken, he was not able to raise the siege; and if he came after, and so too late, he fell into the hands of Joshua:
and Joshua smote him, and his people, until he had left him none
remaining;
destroyed him and all his army, so that there were none left to return and relate their unhappy case.
