Gilgal

This is the place of My throne and the place for the soles of My feet... Ezekiel 43:7

Before circumcision was a mitzvah, it was a cultural marker: Thus Joshua introduces circumcision to Israel at Gilgal (Joshua 5:2-9), Jacob’s sons insist that the Shechemites circumcise before Shechem marries their sister (Genesis 34), and the Israelites scorn the Philistines for being uncircumcised (Judges 14:3).
