'Tamarisk tree' in the Bible

Abraham planted a tamarisk tree in Beer-sheba, and there he called on the name of Yahweh, the Everlasting God.

Saul heard that David and his men had been discovered. At that time Saul was in Gibeah, sitting under the tamarisk tree at the high place. His spear was in his hand, and all his servants were standing around him.

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