CHAPTER 16

2Ch 16:1-14. Asa, by a League with the Syrians, Diverts Baasha from Building Ramah.

1-6. In the six and thirtieth year of the reign of Asa, Baasha ... came up against Judah--Baasha had died several years before this date (1Ki 15:33), and the best biblical critics are agreed in considering this date to be calculated from the separation of the kingdoms, and coincident with the sixteenth year of Asa's reign. This mode of reckoning was, in all likelihood, generally followed in the book of the kings of Judah and Israel, the public annals of the time (2Ch 16:11), the source from which the inspired historian drew his account.

Baasha ... built Ramah--that is, fortified it. The blessing of God which manifestly rested at this time on the kingdom of Judah, the signal victory of Asa, the freedom and purity of religious worship, and the fame of the late national covenant, were regarded with great interest throughout Israel, and attracted a constantly increasing number of emigrants to Judah. Baasha, alarmed at this movement, determined to stem the tide; and as the high road to and from Jerusalem passed by Ramah, he made that frontier town, about six miles north of Asa's capital, a military station, where the vigilance of his sentinels would effectually prevent all passage across the boundary of the kingdom (see on 1Ki 15:16-22; also Jr 41:9).
