With whom my hand shall be established: mine arm also shall strengthen him.
God's hand was to be firmly established with David's promised ruler, remaining with him to uphold him, and God's own arm was to make him strong. This pledge was part of the covenant promises made to David, promises that were not limited to his immediate lifetime but stretched forward into eternity. Its full and complete fulfillment was to be realized in Christ as the ultimate heir of that covenant.
