In the nine and thirtieth year of Azariah king of Judah began Menahem the son of Gadi to reign over Israel,.... Shallum reigning but one month, both their reigns began the same year.
MENAHEM'S REIGN. (2-Kings 15:17-21)
reigned ten years in Samaria--His government was conducted on the religious policy of his predecessors.
Reign of Menahem. - Menahem's reign lasted ten full years (see at 2-Kings 15:23), and resembled that of his predecessors in its attitude towards God. In 2-Kings 15:18, the expression כּל־ימיו (all his days) is a very strange one, inasmuch as no such definition of time occurs in connection with the usual formula, either in this chapter (cf. 2-Kings 15:24 and 2-Kings 15:28) or elsewhere (cf. 2-Kings 3:3; 2-Kings 10:31; 2-Kings 13:2, 2-Kings 13:11, etc.). The lxx have instead of this, ἐν ταῖς ἡμέραις αὐτοῦ (in his days). If we compare 2-Kings 15:29, בּא פּקח בּימי (in the days of Pekah came, etc.), בּא בּימיו might possibly be regarded as the original reading, from which a copyist's error בּא כּל־מיו arose, after which כּל־ימיו was connected with the preceding clause.
