Shammah is a name mentioned several times in the Hebrew Bible.
After the Israelites fled from the troop of Philistines, Shammah stood alone and defeated them himself.
He is credited with having single-handedly defeated these Philistine soldiers at a lentil patch.
[1] It is also possible Shammah is mentioned in Judges as Shamgar, who defeated 600 men of the Philistines with an ox goad.
There are other people named Shammah in the Bible who are mentioned only in passing.
