'Tamarisk' in the Bible

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.

Then they took their bones and buried [them] under the tamarisk in Jabesh, and they fasted [for] seven days.
