Not is all good with the Tamarisk Tree?
King Sauls madness is related to this type of tree in Jabesh-Gilead, when he waited to kill the boy David out of jealousy, because David was being praised by others more than he was!
1 Samuel 22:6, 31:13.
But as for Jabesh-Gilead, this place name is found across several books of the Old Testament. Judges, 1 Samuel, 2 Samuel, 2 Kings and 1 Chronicles.
All this will make for a good bible study if you can make the time?
