Luke 10:1

After these things the Lord appointed seventy others also, and sent them two by two before his face into every city and place, where he himself would come.

Augustine of Hippo

AD 430
As also in twenty-four hours the whole world moves round and receives light, so the mystery of enlightening the world by the Gospel of the Trinity, is hinted at in the seventy-two disciples. For three times twenty-four makes seventy-two. Now as no one doubts that the twelve Apostles foreshadowed the order of Bishops, so also we must know that these seventy-two represented the presbytery, (that is, the second order of priests.) Nevertheless, in the earliest times of the Church, as the Apostolicalwritings bear witness, both were called presbyters, troth also c ailed bishops, the former of these signifying “ripeness of wisdom,” the latter, “diligence in the pastoral care.”

Basil the Great

AD 379
At the same time it is implied by this, that if any are equal in spiritual gifts, they should not suffer a fondness for their own opinion to get the better of them.

Bede

AD 735
Rightly are seventy-two sent, for toso many nations of the world was the Gospel to be preached, that as at first twelve were appointed because of the twelve tribes of Israel, so, these also were ordained as teachers forthe instruction of the foreign nations. Now as the great harvest is this whole multitude of believers, so the few laborers are the Apostles, and their followers who are sent to this harvest.

Bede

AD 735
The number of the twelve apostles marked the beginning of the episcopal rank. It is also apparent that the seventytwo disciples, who were also sent out by the Lord to preach the word, signify in their selection the lesser rank of the priesthood that is now called the presbyterate. For the same reason, it is appropriate that these seventytwo figured in the last part of the priestly clothing, as those twelve had been in the first. It was fitting that the type of those who would occupy a higher rank in the body of the High Priest (that is, in the church of Christ) should have a higher place in the typical clothing of the Old Testament high priest.

After these things the Lord also. Seventy-two. Vulgate. Dorotheus and others profess to give their names, but Eusebius declares that he knew of no written list of these seventy disciples, although the names of some might be gathered from the Acts of the Apostles, e.g, Matthias and Barsabas, Acts i.; Stephen and the other Deacons, Acts vi.; Ananias and Barnabas, Acts iv.; Mnason, Acts xxi, and others. Here observe, 1. That as Moses at the beginning of his leadership chose elders or princes for the twelve tribes of Israel and afterwards, by reason of the increase of the people and of the cares of government, made a further choice of six from each tribe, i.e. of seventy-two, to act as rulers: so Christ ordained that each tribe, should have its Apostle, and six presbyters or elders, for such were these disciples, who were commanded to go throughout all Juda, preaching that the kingdom of God and of Christ was nigh, and confirming their preaching by miracles, that so the work of the Apostl...

Cyril of Alexandria

AD 444
An outline of this ordinance also was set forth in the words of Moses, who at the command of God chose out seventy, upon whom God poured out His Spirit. In the book of Numbers also it was written of the children of Israel, that they came to Elim, which is by interpretation&#8220;ascent,&#8221; and there were there twelve fountains of water, and seventy palm trees. For whenwe fly to spiritual refreshment, we shall find twelve fountains, namely, the holy Apostles, from whom we imbibe the knowledge of salvation as from the well-springs of the Savior; and seventy palms, that is, those who were now appointed by Christ. For the palm is a tree of sound core, striking deep root and fruitful, always growing by the water side, yet at the sametime putting forth its leaves upwards. As the large fields require many reapers, so also do the multitude of believers in Christ. Hence He adds, Pray you therefore the Lord of the harvest, that he would send forth laborers into his harvest. Now mark that whe...

Eusebius of Caesarea

AD 339
The names of the apostles of the Savior are clear to everyone from the Gospels, but no list of the seventy disciples is in circulation anywhere. Some have said, to be sure, that Barnabas was one of them, and the Acts of the Apostles and Paul writing to the Galatians have made special mention of him. They say Sosthenes was of these as well. Together with Paul, he wrote to the Corinthians. Tradition also holds that Matthias, who was listed among the apostles in place of Judas, and Joseph Justus, who was honored with him at the same casting of lots, were considered worthy of the same calling among the seventy. They say that Thaddaeus was also one of them, about whom I shall presently relate a story which has come down to us. On observation, you would find that the disciples of the Savior appear to have been more than the seventy. Paul says that after the resurrection from the dead Cephas saw him first, then the Twelve. After these saw him, he was seen by more than five hundred brothers al...

Other seventy-two. Most Greek copies, and the Syriac version, have seventy, as in the Protestant translation. Yet there seems no doubt but the true number was seventy-two. For seventy-two may be called seventy; but had they been only seventy, they could never have been called seventy-two. This was also the exact number of the judges chosen to assist Moses; (Exodus xxiv. 1.) though called seventy, (Numbers xi. 16.) as it is evident, because there were six chosen out of every one of the twelve tribes. In like manner the exact number of the interpreters called the Septuagint must have been seventy-two; and also the just number of the Sanhedrim. Two and two, that one might be a help and comfort to the other; as also a witness of the carriage and behaviour of his companion. (Witham)

Gregory The Dialogist

AD 604
He sends the disciples to preach two and two, because there are two command; of charity, the love of God, and love of our neighbor;(and charity cannot exist without at least two;) thereby silently suggesting to us, that he who has not love to another, ought not to undertake the office of preaching. It is rightly added, before his face into every city and place, whither he himself would come. Forthe Lord follows His preachers, since the preaching comes first, and then the Lord enters into the tabernacle of our heart; seeing, that through the words of exhortation going before, truth is received into the mind. Hence Esaias says to the preachers, Prepare you the way of the Lord, make straight a highway for our God. But not without deep sorrow can we add, but the laborers are few. For although there are who would hear good things they are wanting who should spread them. Behold the world is full of priests, but seldom is there found a laborer in God's harvest, because we undertake indeed the...

John Chrysostom

AD 407
But how does He give the name of harvest to awork only just now at its beginning? the plough not yet put down, nor the furrows turned, Heyet speaks of harvests, for His disciples might waver and say, how can we so small a number convert the whole world how can foolish men reform the wise, naked men those that arearmed, subjects their rulers? Lest they should be disturbed then by such thoughts, He calls the Gospel a harvest; as if He says, All things are ready, I send you to a gathering of fruits already prepared. You can sow and reap the same day. As then the husbandmen goes out to harvest rejoicing, much more also and with greater cheerfulness must you go out into the world. For this is the true harvest, which shows the fields all prepared for you. But he afterwards increased them greatly, not by adding to their number, but awarding to them power. He implies that it is a great gift to send laborers into the divine harvest, by His saving that the Lord of the harvest must be prayed to u...

Theophilus of Antioch

AD 184
The Lord had appointed the disciples forthe sake of the multitude, who were in want of teachers. For as our corn fields require many reapers, so the innumerable company of those who are to believe need many teachers, as it follows, The harvest truly is great.
