Albert Barnes Commentary 2 Kings 8:2

"And the woman arose, and did according to the word of the man of God; and she went with her household, and sojourned in the land of the Philistines seven years." — 2 Kings 8:2 (ASV)

The country of the Philistines—the rich, low, grain-growing plain along the seacoast of Judah—was always a land of plenty compared with the highlands of Palestine. Moreover, if food failed there, it was easily imported by sea from neighboring Egypt.
