What was the name of Jonathan's son whom King David provided for?

The name of Jonathan’s son whom King David provided for was Mephibosheth. He was the son of Jonathan and grandson of Saul, Israel’s first king.

According to 2 Samuel, Mephibosheth was five years old when Saul and Jonathan died at the Battle of Mount Gilboa. His nurse fled with him, and he was injured in the accident, leaving him unable to walk. He later lived at Lo-debar, east of the Jordan River.

After David became king, he searched for a surviving member of Saul’s family to whom he could show kindness because of his covenant with Jonathan. David restored Saul’s former land to Mephibosheth and invited him to eat regularly at the royal table. The gesture was unusual because royal succession disputes could make surviving relatives political threats.

A common mix-up is that Mephibosheth is also called Meribaal in Chronicles. These names refer to the same son of Jonathan, although the form Mephibosheth is the one most commonly used in this story.
