Charles Spurgeon Commentary Titus 1:6-12

"if any man is blameless, the husband of one wife, having children that believe, who are not accused of riot or unruly. For the bishop must be blameless, as God`s steward; not self-willed, not soon angry, no brawler, no striker, not greedy of filthy lucre; but given to hospitality, as lover of good, sober-minded, just, holy, self-controlled; holding to the faithful word which is according to the teaching, that he may be able to exhort in the sound doctrine, and to convict the gainsayers. For there are many unruly men, vain talkers and deceivers, specially they of the circumcision, whose mouths must be stopped; men who overthrow whole houses, teaching things which they ought not, for filthy lucre`s sake. One of themselves, a prophet of their own, said, Cretans are always liars, evil beasts, idle gluttons." — Titus 1:6-12 (ASV)

One of themselves, even a prophet of their own, (Titus 1:6–12)

According to Jerome, this was Epimenides, a prophet-poet, who lived in Crete in the sixth century before Christ.
