Matthew Henry on 2 Chronicles 16:1-6
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?
