Verse 9. -
Thy master's son. Strictly Mephibosheth was Saul's grandson, but words of relationship are used in a very general way in Hebrew.
9:9-13 As David was a type of Christ, his Lord and Son, his Root and Offspring, let his kindness to Mephibosheth remind us of the kindness and love of God our Saviour to fallen man, to whom he was under no obligation, as David was to Jonathan. The Son of God seeks this lost and ruined race, who sought not after him. He comes to seek and to save them!
Then the king called to Ziba, Saul's servant,.... Who had been his servant:
and said unto him, I have given unto thy master's son; meaning either, as some, the son of Mephibosheth, Micha after mentioned; or rather Mephibosheth himself, the grandson of Saul, whose servant Ziba had been:
all that pertained to Saul, and to all his house; all his paternal estate, or what he had acquired, or in any wise belonged to him and his family; which David had in possession, and which he readily and cheerfully delivered up to Mephibosheth, having so great a regard to the memory of his father.
