It is the northernmost mountain in the region of Israel. Currently, it is on the border of Lebanon and Syria.
Its height is very great, so its summit is always covered with perpetual snow. The melted water from here flows to form the Jordan River, passing through the Sea of Galilee in the middle and flowing all the way to the Dead Sea.
It is also called Mount Helmon.
It is also called Sirion.
Deuteronomy 3:9(The Sidonians call Mount Hermon Sirion, while the Amorites call it Senir.)
