'Tamarisk tree' in the Bible

Abraham planted a tamarisk tree at Beersheba, and there he called on the name of the Lord, the Everlasting God.

Then Saul heard that David and the men who were with him had been discovered. Now Saul was sitting in Gibeah, under the tamarisk tree on the height with his spear in his hand, and all his servants were standing around him.

They took their bones and buried them under the tamarisk tree at Jabesh, and fasted seven days.
