There is a league between me and thee, as there was between my father and thy father: behold, I have sent thee silver and gold; go, break thy league with Baasha king of Israel, that he may depart from me.
How to reconcile the date of this event with the history of the kings I am quite at a loss. Baasha died in the twenty-sixth year of Asa, Kg1 16:8. How then could this be done in his thirty-sixth year, when Baasha's family was quite cut off, and Omri was upon the throne?
Commenting on 2 Chronicles 16:1-6
[There is] a league between me and thee, as [there was] between my father and thy father: behold, I have sent thee silver and gold; go, break thy league with Baasha king of Israel, that he may depart from me.
There is a league - Let there be a treaty, offensive and defensive, between me and thee: see on Kg1 15:22 (note).
