Easton's Bible Dictionary (1897)
A chaplet, the original seat of the Philistines (Deut. 2:23; Jer. 47:4; Amos 9:7). The name is found written in hieroglyphics in the temple of Kom Ombos in Upper Egypt. But the exact situation of Caphtor is unknown, though it is supposed to be Crete, since the Philistines seem to be meant by the “Cherethites” in 1 Sam. 30:14 (see also 2 Sam. 8:18). It may, however, have been a part of Egypt, the Caphtur in the north Delta, since the Caphtorim were of the same race as the Mizraite people (Gen. 10:14; 1 Chr. 1:12).
Hastings' Dictionary of the Bible (1898) & Schaff's Bible Dictionary
CAPH'TOR (chaplet), the original home of the Caphtorim or Philistines. Deut 2:23; Jer 47:4; Am 9:7. Some have placed it in Cappadocia, others in Cyprus or in Crete. It is more probably identical with Caphtur, and the northern delta of Egypt.
