Shikkeron
Shikkeron is a location on the northern border of the territory allotted to the tribe of Judah, mentioned once in UPDV at Joshua 15:11: "the border extended to Shikkeron, and passed along to mount Baalah, and went out at Jabneel."
It marks a boundary point between Ekron and Mount Baalah in the description of Judah's northern border running toward the Mediterranean coast.
