The day — Which God hath set, and appointed for their ruin. Caphtor — Tyre and Sidon were neighbours to the Philistines, and so were often called to their help. The Philistines and Caphtorim were related, for their first progenitors, Philistim and Caphtorim, were both the sons of Mizriam the son of Ham, one of the sons of Noah.
