And the king said, [is] there not yet any of the house of Saul;
 that is, remaining or living: 
 that I may show the kindness of God unto him?
 great kindness, some large favour or benefit; for the word God added to things, as to trees, mountains serves to set forth the excellency of them; and this kindness is in imitation of God, or such as he had sworn in the presence of God to show; and that is expressed in the same language, ( 1 Samuel 20:14 ) ; 
 and Ziba said unto the king, Jonathan hath yet a son;
 a son still living; 
 [which is] lame on [his] feet;
 on both his feet, as the Targum; of which occasion, (See Gill on 2 Samuel 4:4).
