Ach'sah (Heb. Aksah', עִכסָה, anklet; Sept. Α᾿χσά), the daughter of Caleb (and apparently his only daughter, 1Ch 2:49, "Achsa"), whose hand her father offered in marriage to him who should lead the attack on the city of Debir, and take it, B.C. 1612. The prize was won by his nephew Othniel; and as the bride was conducted with the usual ceremony to her future home, she alighted from the ass which she rode, and sued her father for an addition of springs of water (as being peculiarly necessary, Stanley, Palest. p. 161) to her dower in lands, which were situated in the southern part of Judah SEE GULLOTH. It is probable that custom rendered it unusual, or at least ungracious, for a request tendered under such circumstances by a daughter to be refused, and Caleb accordingly bestowed upon her "the upper and the nether springs" (Jos 15:16-19; Jg 1:9-15).
