'Tamarisk tree' in the Bible

Abraham planted a tamarisk tree in Beersheba, and called there on the name of Yahweh, the Everlasting God.

Saul heard that David was discovered, and the men who were with him. Now Saul was sitting in Gibeah, under the tamarisk tree in Ramah, with his spear in his hand, and all his servants were standing about him.

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