“Let there be a treaty between me and you as there was between my father and your father. See, I have sent you silver and gold. Now go and break your treaty with Baasha king of Israel, so that he will withdraw 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).
