Why was the word "Bishop" used in Titus 1:7 and 1 Peter 2:25 [KJV] instead of "Guardian" / "Episkopon" (Ἐπίσκοπον)?
1 Peter 2:25 [KJV]
[25] "For ye were as sheep going astray; but are now returned unto the Shepherd and Bishop of your souls."
Titus 1:7 [KJV]
[7] "7 For a bishop must be blameless, as the steward of God; not selfwilled, not soon angry, not given to wine, no striker, not given to filthy lucre".
In the original Greek text of 1 Peter 2:25 & Titus 1:7, we do not find the word "Bishop". - Instead of Bishop, the word "Guardian" / "Episkopon" ( ἐπίσκοπον ) is used.
Why did the KJV use a Bishop instead of simply stating a Guardian or "Episkopon"?
