Eusebius, H.E. 3.24.6
"Matthew had first preached to Hebrews, and when he was on the point of going to others he transmitted in writing in his native language the Gospel according to himself, and thus supplied by writing the lack of his own presence to those from whom he was sent."
Jerome also asserts that Matthew wrote in the Hebrew language (Epist. 20.5), and he refers to a Hebrew Matthew and a Gospel of the Hebrews-unclear if they are the same. He also quotes from the Gospel used by the Nazoreans and the Ebionites, which he says he has recently translated from Hebrew to Greek (in Matth. 12.13).
Origen (Eusebius, H.E. 6.25.4)
"As having learnt by tradition concerning the four Gospels, which alone are unquestionable in the Church of God under heaven, that first was written according to Matthew, who was once a tax collector but afterwards an apostle of Jesus Christ, who published it for those who from Judaism came to believe, composed as it was in the Hebrew language."
Papias (Eusebius, H.E. 3.39.16)
"Matthew collected the oracles (ta logia) in the Hebrew language, and each interpreted them as best he could."
Irenaeus, Adv. Haer. 3.1.1
"Matthew also issued a written Gospel among the Hebrews n their own dialect while Peter and Paul were preaching at Rome and laying the foundations of the church."
Pantaenus, a church historian and missionary who traveled to India in 180 A.D., discovered the copy of the Gospel of Matthew in Hebrew that Bartholomew had taken with him.
"It is reported," wrote Eusebius, a fourth century bishop and church historian, "that among person there who knew Christ, (Pantaenus) found the Gospel according to St. Matthew (... which had arrived ahead of Pantaenus by more than a century). For Bartholomew, one of the apostles, had preached to them, and left them (in India) the writing of Matthew in the Hebrew language which they had preserved."
