After David had conquered the enemies of Israel, 2 Samuel 8:14, and settled in as king over Israel, he appears to have learned that Mephibosheth, Johnathon’s son, who as a five-year-old was crippled, is still alive, 2 Samuel 4:4.
Mephibosheth’s real name was Meribbaal or Meribaal, 1 Chronicles 8:34 / 1 Chronicles 9:40. By this time Mephibosheth had grown up, got married and had become the father of a young son Mica.
This was an occasion when David remembered his covenant with Jonathan, 1 Samuel 18:3 / 1 Samuel 20:1-4 / 1 Samuel 20:14-17, and so, looking for anyone who might be an heir of Jonathan through whom he could preserve Jonathan’s posterity. This shows us how David is a man of his word and a man of honour.
Although David asks the question, no one is able to answer, but someone else tells him about Ziba, who was a close relative of Saul. Ziba appears to be in full possession of all the properties of the former king, Saul, but as Machir had been caring for Mephibosheth, it seems likely that Ziba had made himself quite wealthy in those intervening years after Saul’s death.
Lo Debar was located in north-eastern Palestine east of the Jordan River and not far from Mahanaim, which was Ish-Bosheth’s capital. Ammiel is mentioned in 1 Chronicles 3:5 as the father of Bathsheba, the mother of Solomon and so Machir was Bathsheba’s brother, making him a brother-in-law of King David.
It appears that Machir was a very wealthy person and because he loved Saul’s family, took Mephibosheth into his home and cared for him. This tells us that Machir was a very faithful and generous person, and later helped David when Absalom rebelled against him, 2 Samuel 17:27-29.
It’s clear that when Mephibosheth appeared in front of David, he was fearful for his life, as he bowed down. Understandably, he would be nervous about this meeting because it was common practice that any heir to the former king was to be killed.
Mephibosheth calls himself a dead dog, which was used as an exaggeration of the truth, 1 Samuel 24:14, and he realises that he wasn’t called to David to be killed but to be rewarded so that Johnathon’s name may continue in Israel. Mephibosheth is very humbled by all this, he knows he doesn’t deserve mercy, but he receives it.
Because Mephibosheth was disabled on both feet, Ziba was asked to continue to look after Mephibosheth and bring the produce of the fields to Mephibosheth, in other words, everything which belonged to Jonathan was to be returned to Mephibosheth. Later, Mephibosheth’s descendants would become prominent leaders within the tribe of Benjamin, 1 Chronicles 8:35-40 / 1 Chronicles 9:40-44.
Although Ziba appears to be sincere here, it wouldn’t be too long before he betrays David and rebels against him, 2 Samuel 16-20.
