Leviticus 19:27 "'You shall not cut the hair on the sides of your heads, neither shall you clip off the edge of your beard. (WEB NIV)
Jeremiah 9:26 Egypt, and Judah, and Edom, and the children of Ammon, and Moab, and all that have the corners of their hair cut off, who dwell in the wilderness; for all the nations are uncircumcised, and all the house of Israel are uncircumcised in heart. (See NAS)
