"They buried him under the oak in Jabesh"  (1 Chronicles 10:12).  This tree was called "a tamarisk tree" in  1 Samuel 31:13; and the marginal reference here gives "terebinth" as an alternative.  If the trees were growing side by side, which is by no means impossible, the Biblical accounts may both be absolutely accurate.  No one has the right to deny what is here stated as a fact.
