David and Jonathan enter into a parity covenant, exchanging robes and weapons to signify their bond of loyalty to each other. The covenant they cut includes Jonathan’s young son Mephibosheth, whom David seeks out to bless even after Jonathan dies. Thereafter, Mephibosheth is invited to eat at the king’s table forever, unworthy though he may be. David shows Mephibosheth hesed (loving-kindness) because of his covenant with Jonathan, who served as his son’s covenant representative head.
This historical episode illustrates well the concept of representation. As Jonathan was Mephibosheth’s covenant representative head, so Jesus is the covenant representative head of the entire human race. Moreover, like David looking for Mephibosheth, God is searching for us, wanting to lavish upon us all the riches and blessings that come from being in covenant with him through Christ. He invites us to eat at the King’s table forever, unworthy though we may be. God’s hesed (lovingkindness) now flows to all who acknowledge Jesus by faith as their covenant representative head.
