1 Kings 14:14

“ Moreover YHWH will raise him up a king over Israel, who will cut off the house of Jeroboam that day. But what? Even now.”

Furthermore it was YHWH’s intention to raise up a king over Israel who would cut off the house of Jeroboam ‘in that day’. In other words, when in the course of events Jeroboam’s house was smitten by a claimant to the throne, they were to recognise that it was of YHWH. For in the end all history is in His hands.

“But what? Even now.” The simplest explanation of these abrupt words is that they signify ‘But what shall we say? He has done it even now’. In other words YHWH would not only do it in some unknown future, but was even at this time bringing it about.
