And was unknown by face. This appears to be added for the sake of shewing more strongly the wickedness and malignity of his slanderers. If the churches of Judea who had only heard respecting him, were led to give glory to God for the astonishing change which he had wrought in Paul, how disgraceful was it that those who had beheld the fruits of his amazing labors should not have acted a similar part! If the mere report was enough for the former, why did not the facts before their eyes satisfy the latter?

And was unknown by face - Paul had visited Jerusalem only, and he had formed no acquaintance with any of the churches in the other parts of Judea. He regarded himself at the first as called to preach particularly to the Gentiles, and he did not remain even to form an acquaintance with the Christians in Judea.
The churches of Judea - Those which were out of Jerusalem. Even at the early period of the conversion of Paul there were doubtless many churches in various parts of the land,
Which were in Christ - United to Christ; or which were Christian churches. The design of mentioning this is, to show that he had not derived his views of the gospel from any of them. He had neither been instructed by the apostles, nor was he indebted to the Christians in Judea for his knowledge of the Christian religion.

And was unknown by face - I was not personally acquainted with any of the Churches of Judea; I was converted in another place, and had not preached the Gospel in any Christian congregation in that country; I knew only those at Jerusalem.

And was unknown by face,.... Or "in person". This is said to prevent what might be objected, that though the apostle had not received the Gospel he preached from any of the apostles at Jerusalem; yet he might have had it from the churches that were in the land of Judea, and from some of the principal men in them; but this was so far from being truth, that he was not so much as known unto the churches of Judea which were in Christ; for there was not only a famous church of believers in Christ at Jerusalem, the metropolis of the land, but there were several congregated churches in the several parts of that country: by Judea we are to understand that part of the land of Israel so called, which was distinct not only from Samaria; but from Galilee and Perea, or the country beyond Jordan; for according to the Jews (d), the land of Israel was divided into three parts, Judea, Perea, and Galilee. Judea again was divided into three parts, the hill country, the plain, and the valley; and the plain of Lydda is as the plain of the south, and its mountainous part as the king's mountain; from Bethhoron to the sea is one province: and elsewhere (e) it is said, that the hill country of Judea is the king's mountain, the plain of it is the plain of the south, and the valley is from Engedi to Jericho--from Bethhoron to Emmaus is mountainous, from Emmaus to Lydda is a plain, and from Lydda to the sea a valley; from which may be collected where this country lay, and where were these churches here spoken of; the foundation of which might be laid in the conversion of some in those parts, through the ministry of the disciples of Christ, who were appointed witnesses of him not only in Jerusalem, but in all Judea and Samaria, Acts 1:8 and about the time of the Apostle Paul's conversion, and his being at Jerusalem, there were churches gathered in Judea, as distinct from Galilee and Samaria, Acts 9:31 particularly at Caesarea, Lydda, Saron, and Joppa. It is very likely that all the apostles, when they first set out to preach the Gospel after the ascension of Christ and the effusion of the Spirit, began in Judea; though some might make a very short stay, and others a longer. The Apostle and Evangelist Matthew is generally thought to have exercised his ministry chiefly in Judea, and to have continued there long; here he wrote his Gospel for the sake of the Jews that believed (f); and that, as a very ancient writer says (g), when Peter and Paul preached at Rome, and founded the church there. Judas Thaddaeus is also said (h) to go through Judea, Galilee, Samaria, Arabia, Syria, and Mesopotamia; and certain it is, that Philip, after he had baptized the eunuch, preached in all the cities from Azotus to Caesarea, where he seems to have stayed awhile and preached, Acts 8:40 and where afterwards was a Gospel church state, of which See Gill on Acts 10:48 and at Lydda and Saron, which were both in Judea, there were saints who were visited by the Apostle Peter, and others converted by him, about the time that our apostle here refers to; of the church at Lydda; See Gill on Acts 9:32 at Joppa also, which was in the tribe of Daniel, there were disciples at the same time, and very likely a church there; See Gill on Acts 9:38 and it may be observed that the Apostle Peter was the minister of the circumcision, he had the Gospel of the circumcision committed to him, and he continued with and preached much to the circumcised Jews; and so in all likelihood was the instrument of planting the churches in Judea here spoken of. These are said to be
in Christ, as the church at Thessalonica, and that at Corinth are elsewhere said to be; because they professed to believe in Christ, were called by his name, and called upon his name; and though every individual member of them might not be in Christ, really united to him, and have communion with him; yet since they were all under a profession of him, they are considered as in him. The Arabic version reads it, "the churches of Judea which believe in Christ"; which though not a literal translation, gives the true sense of the passage, and distinguishes those churches from the synagogues or assemblies of the Jews which did not believe in Christ.

So far was I from being a disciple of the apostles, that I was even unknown in the churches of Judea (excepting Jerusalem, Acts 9:26-29), which were the chief scene of their labors.
