SEV Biblia, Chapter 22:15
Porque has de ser testigo suyo a todos los hombres, de lo que has visto y oído.
Clarke's Bible Commentary - Acts 22:15
Verse 15. Thou shalt be his witness unto all] Thou shalt proclaim Christ crucified, both to Jews and Gentiles.
John Gill's Bible Commentary
Ver. 15. For thou shalt be his witness unto all men , etc.] Gentiles as well as Jews, an eye and an ear witness to them; of what thou hast seen and heard ; as that he saw him personally and alive, and so could witness to the truth of his resurrection; for after he had been seen by all the apostles, he was last of all seen of Paul; and also, that he heard him and received from him the Gospel, and a mission and commission to preach it; for what he preached he did not receive of man, nor was he taught it by any, but he had it by revelation from Jesus Christ.
Matthew Henry Commentary
Verses 12-21 - The apostle goes on to relate how he was confirmed in the change he ha made. The Lord having chosen the sinner, that he should know his will he is humbled, enlightened, and brought to the knowledge of Christ an his blessed gospel. Christ is here called that Just One; for he is Jesus Christ the righteous. Those whom God has chosen to know his will must look to Jesus, for by him God has made known his good-will to us The great gospel privilege, sealed to us by baptism, is the pardon of sins. Be baptized, and wash away thy sins; that is, receive the comfor of the pardon of thy sins in and through Jesus Christ, and lay hold of his righteousness for that purpose; and receive power against sin, for the mortifying of thy corruptions. Be baptized, and rest not in the sign, but make sure of the thing signified, the putting away of the filth of sin. The great gospel duty, to which by our baptism we ar bound, is, to seek for the pardon of our sins in Christ's name, and i dependence on him and his righteousness. God appoints his labourer their day and their place, and it is fit they should follow his appointment, though it may cross their own will. Providence contrive better for us than we do for ourselves; we must refer ourselves to God's guidance. If Christ send any one, his Spirit shall go along with him, and give him to see the fruit of his labours. But nothing can reconcile man's heart to the gospel, except the special grace of God.

Vincent's NT Word Studies
15. All men. He keeps back the offensive word Gentiles (ch. ix. 15).
Robertson's NT Word Studies
22:15 {A witness for him} (martus autwi). As in #1:8. {Of what} (hwn). Attraction of the accusative relative ha to the genitive case of the unexpressed antecedent toutwn. {Thou hast seen and heard} (hewrakas, present perfect active indicative kai ekousas, first aorist active indicative). this subtle change of tense is not preserved in the English. Blass properly cites the perfect hewraka in #1Co 9:1 as proof of Paul's enduring qualification for the apostleship.
