'Tamarisk tree' in the Bible

And he planted a tamarisk tree in Beersheba, and there he called on the name of Yahweh, {the everlasting God}.

Now Saul heard that David and the men who [were] with him had been located. Saul [was] sitting at Gibeah under the tamarisk [tree] at Ramah. Now his spear [was] in his hand and all his servants [were] stationed around him.
