11 Ziba replied, "Yes, my lord the king; I am your servant, and I will do all that you have commanded." And from that time on, Mephibosheth ate regularly at David's table, like one of the king's own sons. 12 Mephibosheth had a young son named Mica. From then on, all the members of Ziba's household were Mephibosheth's servants. 13 And Mephibosheth, who was crippled in both feet, lived in Jerusalem and ate regularly at the king's table.

(Read 2 Samuel 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!
