Elisha spoke to the woman whose son he had brought back to life: "You and your household must go away and live wherever you can, because the LORD has called for a famine. It is coming to the land and will last seven years."
References for 2 Kings 8:1
So the woman went and did what the man of God asked. She and her household moved away, living in Philistia seven years.
When seven years had passed, the woman returned from Philistia. She went to appeal to the king for her house and her farmland.
The king was speaking to Gehazi, the man of God's servant, asking him, "Tell me about all the great things Elisha has done."
So Gehazi was telling the king how Elisha had brought the dead to life. At that very moment, the woman whose son he had brought back to life began to appeal to the king for her house and her farmland. Gehazi said, "Your Majesty, this is the woman herself! And this is her son, the one Elisha brought to life!"
The king questioned the woman, and she told him her story. Then the king appointed an official to help her, saying, "Return everything that belongs to her, as well as everything that the farmland has produced, starting from the day she left the country until right now."
