Another descendant of Saul was Jonathan's son Mephibosheth, who was five years old when Saul and Jonathan were killed. When the news about their death came from the city of Jezreel, his nurse picked him up and fled; but she was in such a hurry that she dropped him, and he became crippled.
You, your sons, and your servants will farm the land for your master Saul's family and bring in the harvest, to provide food for them. But Mephibosheth himself will always be a guest at my table.” (Ziba had fifteen sons and twenty servants.)
When Mephibosheth, the son of Jonathan and grandson of Saul, arrived, he bowed down before David in respect. David said, “Mephibosheth,” and he answered, “At your service, sir.”
“Don't be afraid,” David replied. “I will be kind to you for the sake of your father Jonathan. I will give you back all the land that belonged to your grandfather Saul, and you will always be welcome at my table.”
and Jonathan said to David, “May the Lord God of Israel be our witness! At this time tomorrow and on the following day I will question my father. If his attitude toward you is good, I will send you word.
Then Jonathan said to David, “God be with you. The Lord will make sure that you and I, and your descendants and mine, will forever keep the sacred promise we have made to each other.” Then David left, and Jonathan went back to the town.
