Achish was a king of Gath, one of the five principal cities of the Philistines. He appears in the biblical accounts of David during the final years of Saul and may also be the king named Achish during Solomon's reign.
David first encountered a king named Achish when he fled from Saul and sought safety in Philistine territory. The servants of Achish recognized David as the Israelite warrior celebrated for his victories over the Philistines.
Fearing for his life, David pretended to be insane. Achish dismissed him, and David escaped.
Later, David returned to Gath with approximately six hundred men and their families. This time Achish welcomed him. David had become an enemy of Saul, and the Philistine king apparently considered him a potentially valuable ally.
David initially lived in Gath but requested permission to settle in a smaller town. Achish granted him Ziklag, which became David's base of operations.
For sixteen months David and his followers lived in Philistine territory. During this time, David conducted raids against groups south of Judah while allowing Achish to believe that he was attacking settlements associated with Israel.
Achish came to trust David and expected that David would remain loyal to him.
When the Philistine rulers assembled for war against Saul, Achish brought David and his men with his forces. The other Philistine commanders objected strongly, fearing that David might turn against them during battle.
Although Achish defended David, he ultimately yielded to their objections and ordered David to return to Ziklag.
This decision kept David from participating in the battle in which Saul and Jonathan were killed.
A king named Achish son of Maacah appears later in 1 Kings 2, during Solomon's reign. Two servants belonging to Shimei fled to Gath, and Shimei traveled there to recover them.
The Achish of 1 Kings 2 may have been the same ruler who sheltered David, although this would require a lengthy reign. The differing paternal names may represent variations of one name or refer to two kings.
Because the identification remains uncertain, this record includes both references without treating their identity as established.
No contemporary inscription securely identifies the Achish associated with David. He must also be distinguished from Ikausu, a much later king of Ekron whose name is sometimes rendered Achish.
Achish illustrates the political complexity of relationships between Israel and Philistia during the transition from Saul to David. Although Philistine rulers were often enemies of Israel, Achish was willing to shelter David because David's conflict with Saul appeared to serve Philistine interests. The arrangement also reveals that individual Philistine cities had their own kings and political interests.
Achish's decision to give David Ziklag had lasting consequences because the town subsequently became associated with the kingdom of Judah. His story demonstrates how political alliances could cross ethnic and religious boundaries in the ancient Near East.
David first seeks refuge with Achish at Gath. David escapes after pretending to be insane. David later returns with six hundred followers and their families.
Achish grants David the town of Ziklag. David operates from Ziklag while maintaining Achish's confidence. Achish prepares to include David in a campaign against Saul.
Other Philistine commanders reject David's participation. Achish sends David back to Ziklag. A possibly identical Achish appears during Solomon's reign.
Achish plays an important role in the biblical account of David's rise to kingship. His protection allowed David to escape Saul and establish a secure base at Ziklag. The refusal of the other Philistine rulers to accept David in their army also prevented him from participating in the battle that ended Saul's reign.
The account reveals David's difficult position as a future king of Israel living under the protection of a Philistine ruler. Achish also provides an important example of the independence and political influence of individual Philistine city-kings.
