I Samuel 27 The Enemy Of My Enemy Is Useful.
It is ironic that David felt he had to flee to Gath, home of Goliath, in order to escape the wrath of the king of Israel whom he had defended along with the nation. Achish, the king of Gath, actually grants David some territory at Ziklag, thinking that David was on the outs with Saul so was looking for a friendly neighbour. David fooled Achish into thinking he was defending him, all the while he was fighting the LORD’s battles for his people. David got wise though, he would not be allowing any witnesses to return to Achish, so “David would save neither man nor woman alive, to bring news to Gath” (v. 11).
