'Lord Shall' in the Bible

And the LORD shall return his blood upon his own head, who fell upon two men more righteous and better than he, and slew them with the sword, my father David not knowing of it, to wit, Abner the son of Ner captain of the host of Israel, and Amasa the son of Jether, captain of the host of Judah.

Moreover, the LORD shall raise him up a king over Israel, who shall cut off the house of Jeroboam that day: but what? even now.
