I can see the form ϭⲟⲓⲥ under C7376. Where is this coming from?
⳪ and ⲟ̅ⲥ̅ are the only Bohairic forms attested in Crum. The traditional spelling should be ϭⲱⲓⲥ given the Sahidic ϫⲟⲉⲓⲥ. ϭⲱⲓⲥ can also be seen e.g. here.
Modern ecclesiastical books use ϭⲟⲓⲥ, because people were unsure how ⳪ should be spelled out, but this an error.
