John Gill's Bible Commentary Ver. 3. And when they had fasted and prayed , etc.] Not when they had done fasting and praying, at the time the Holy Ghost made an impulse on their minds, to separate two of their brethren to a work they were appointed to; but at another time, which was fixed for that purpose; when they fasted and prayed, not for direction, who they were to set apart and send; for the persons were before pointed out to them, but that they might have every needful gift and qualification for the work, and be succeeded in it: and laid their hands on them ; not as ordaining them, for this was not an ordination; the Apostle Paul particularly was not ordained an apostle by man, but by Jesus Christ; who personally appeared to him, and made and ordained him his minister and apostle; and much less by men inferior to himself, as Simeon, Lucius, and Manaen were; but this was a gesture and ceremony used among the Jews, when they wished any blessing or happiness to attend any persons; and so these prophets, when they separated Paul and Barnabas from their company, and were parting from them, put their hands on them, and wished them all prosperity and success: could this be thought to be an ordination, as it cannot, since both of them were stated and authorized ministers of the word, and one of them an apostle long before this; there might seem some likeness between it and the Jewish ordination of elders, which was done by three f602 , as here were Simeon, Lucius, and Manaen; but then this was not done without the land of Israel, as here, nor by imposition of hands f603 : now when they had thus prayed for them, and wished them well, they sent them away; to do the work they were called unto; not in an authoritative way, but in a friendly manner they parted with them, and bid them farewell.
Matthew Henry Commentary
Verses 1-3 - What an assemblage was here! In these names we see that the Lord raise up instruments for his work, from various places and stations in life and zeal for his glory induces men to give up flattering connexions an prospects to promote his cause. It is by the Spirit of Christ that his ministers are made both able and willing for his service, and take from other cares that would hinder in it. Christ's ministers are to be employed in Christ's work, and, under the Spirit's guidance, to act for the glory of God the Father. They are separated to take pains, and no to take state. A blessing upon Barnabas and Saul in their presen undertaking was sought for, and that they might be filled with the Holy Ghost in their work. Whatever means are used, or rules observed, the Holy Ghost alone can fit ministers for their important work, and cal them to it.

Robertson's NT Word Studies
13:3 {When they had fasted} (nesteusantes). Either finishing the same fast in verse #2 or another one (Hackett), but clearly a voluntary fast. {Laid their hands upon them} (epiqentes tas ceiras autois). Second aorist active participle of epitiqemi. Not ordination to the ministry, but a solemn consecration to the great missionary task to which the Holy Spirit had called them. Whether the whole church took part in this ceremony is not clear, though in #15:40 "the brethren" did commend Paul and Silas. Perhaps some of them here acted for the whole church, all of whom approved the enterprise. But Paul makes it plain in #Php 4:15 that the church in Antioch did not make financial contribution to the campaign, but only goodwill. But that was more than the church at Jerusalem would have done as a whole since Peter had been arraigned there for his activities in Caesarea (#Ac 11:1-18). Clearly Barnabas and Saul had to finance the tour themselves. It was Philippi that first gave money to Paul's campaigns. There were still heathen enough in Antioch, but the church approved the going of Barnabas and Saul, their very best.
