By the same shall he return Whereas he expected to devour the kingdom of Judah at one morsel, and then to proceed farther and conquer Egypt, and other neighbouring countries; and to cut off nations not a few, as is said of him concerning this very time and design, (Isaiah 10:7,) he shall meet with so sad a disappointment and rebuke here, that he shall make haste to return with shame to his own country. For my servant David's sake For my promise and covenant's sake made with David, concerning the stability and eternity of his kingdom, 1 Kings 11:12-13. It must be remembered, that all the promises made to David were made to him in Christ: he and his kingdom were types of the kingdom of Christ. It is to this, and not to the personal merits of David, that the sacred writer here alludes.
