⁴ sn According to the superscription, David wrote this psalm when the Philistines seized him and took him to King Achish of Gath (see 1 Sam 21:11-15).

² sn Pretended to be insane. The psalm heading appears to refer to the account in 1 Sam 21:10-15 which tells how David, fearful that King Achish of Gath might kill him, pretended to be insane in hopes that the king would simply send him away. The psalm heading names the king Abimelech, not Achish, suggesting that the tradition is confused on this point. However, perhaps “Abimelech” was a royal title, rather than a proper name. See P. C. Craigie, Psalms 1-50 (WBC), 278.

³ sn Ziklag was a city in the Negev which had been given to David by Achish king of Gath. For more than a year David used it as a base from which he conducted military expeditions (see 1 Sam 27:5-12). According to 1 Sam 30:1-19, Ziklag was destroyed by the Amalekites while Saul fought the Philistines.

³ sn The Hebrew term translated lunatic applies to anyone who exhibits irrational behavior. It was used for example of David, who drooled and scratched on the city gate to convince Achish not to arrest him as a politically dangerous threat (1 Sam 21:14). It was often used contemptuously of the prophets by those who wanted to play down the significance of their words (2 Kgs 9:11; Hos 9:7, and here).
