Cut off. All the males of the family of Jeroboam were to be put to death, so that his house would perish. This was done by Baasha (ch. 15:29). The phrase used to denote males was a common expression of the period, from the time of David (1 Sam. 25:22, 34), through Baasha (1 Kings 16:11), to Ahab (1 Kings 21:21; 2 Kings 9:8), and is a term of contempt applied to such males as are doomed to utter destruction.
Shut up and left. The meaning of this phrase is not clear, but it is used in connection with the contemptuous term applied to such males as were to be cast away and rooted out (1 Kings 21:21; 2 Kings 9:8), and at times of calamity or adversity (Deut. 32:36; 2 Kings 14:26). The expression seems to be idiomatic, and various meanings have been assigned to it such as (1) married and single, (2) bond and free, (3) precious and vile, (4) minors and those of age.
