C. F. Keil and Franz Delitzsch on 1 Kings 14:14

1Ki 14:14 “Jehovah will raise Himself up a king over Israel, who will cut off the house of Jeroboam this day; but what (sc., do I say)? even now,” sc., has He raised him up. This appears to be the simplest explanation of the last words of the verse, of which very various interpretations have been given. יד is placed before היּום, to give it the stronger emphasis, as in Exo 32:1 (compare Jos 9:12-13, and Ewald, §293, b.; and for עתּה גּם compare Delitzsch on Job, i. p. 290, transl.).
