As I ought to speak; meaning, that to proclaim the truth of the gospel as it ought to be proclaimed, is a high and rare attainment. Every word here deserves to be carefully weighed. Twice he uses the expression boldly, -- "that I may open my mouth boldly," "that therein I may speak boldly." Fear hinders us from preaching Christ openly and fearlessly, while the absence of all restraint and disguise in confessing Christ is demanded from his ministers. Paul does not ask for himself the powers of an acute debater, or, I should rather say, of a dexterous sophist, that he might shield himself from his enemies by false pretences. It is, that I may open my mouth, to make a clear and strong confession; for when the mouth is half shut, the sounds which it utters are doubtful and confused. To open the mouth, therefore, is to speak with perfect freedom, without the smallest dread. But does not Paul discover unbelief, when he entertains doubts as to his own stedfastness, and implores the intercession of others? No. He does not, like unbelievers, seek a remedy which is contrary to the will of God, or inconsistent with his word. The only aids on which he relies are those which he knows to be sanctioned by the Divine promise and approbation. It is the command of God, that believers shall pray for one another. How consoling then must it be to each of them to learn that the care of his salvation is enjoined on all the rest, and to be informed by God himself that the prayers of others on his behalf are not poured out in vain! Would it be lawful to refuse what the Lord himself has offered? Each believer, no doubt, ought to have been satisfied with the Divine assurance, that as often as he prayed he would be heard. But if, in addition to all the other manifestations of his kindness, God were pleased to declare that he will listen to the prayers of others in our behalf, would it be proper that this bounty should be slighted, or rather, ought we not to embrace it with open arms? Let us therefore remember that Paul, when he resorted to the intercessions of his brethren, was influenced by no distrust or hesitation. His eagerness to obtain them arose from his resolution that no privilege which the Lord had given him should be overlooked. How absurdly then do Papists conclude from Paul's example, that we ought to pray to the dead! Paul was writing to the Ephesians, to whom he had it in his power to communicate his sentintents. But what intercourse have we with the dead? As well might they argue that we ought to invite angels to our feasts and entertainments, because among men friendship is promoted by such kind offices.

For which I am an ambassador in bonds - In chains (see the margin); or in confinement. There is something especially touching in this. He was "an ambassador" - sent to proclaim peace to a lost world. But he was now in chains. An ambassador is a sacred character. No greater affront can be given to a nation than to put its ambassadors to death, or even to throw them into prison. But Paul says here that the unusual spectacle was witnessed of an ambassador seized, bound, confined, imprisoned; an ambassador who ought to have the privileges conceded to all such people, and to be permitted to go everywhere publishing the terms of mercy and salvation. See the word "ambassador" explained in the notes on 2-Corinthians 5:20.
That therein - Margin, or "thereof." Greek, ἐν αὐτῷ en autō - "in it;" that is, says Rosenmuller, in the gospel. It means that in speaking the gospel he might be bold.
I may speak boldly - Openly, plainly, without fear; see the notes on Acts 4:13; Acts 9:27, note; Acts 13:46, note; Acts 14:3, note; Acts 18:26, note; Acts 19:8, note; Acts 26:26, note.
As I ought to speak - Whether in bonds or at large. Paul felt that the gospel ought always to be Spoken with plainness, and without the fear of man. It is remarkable that he did not ask them to pray that he might be released. "Why" he did not we do not know; but perhaps the desire of release did not lie so near his heart as the duty of speaking the gospel with boldness It may be of much more importance that we perform our duty aright when we are afflicted, or are in trouble, than that we should be released.

An ambassador in bonds - An ambassador being the representative of his king, his person was in all civilized countries held sacred. Contrary to the rights of nations, this ambassador of the King of heaven was put in chains! He had however the opportunity of defending himself, and of vindicating the honor of his Master. See above.
As I ought to speak - As becomes the dignity and the importance of the subject.

For which I am an ambassador in bonds,.... The character the apostle bore was that of an ambassador; and he was an ambassador from and for Christ, in his room and stead; he represented him, he was sent by him, and entrusted by him with the Gospel; he gave him it, and a commission to preach it, and furnished him with qualifications for it; such as knowledge and faithfulness wisdom and prudence, courage and greatness of mind; and made his embassy successful: and he was chiefly an ambassador to the Gentiles, which showed great condescension in Christ to send him to them, and base ingratitude in the despisers and rejecters of the Gospel, for which he was an ambassador; for the embassy Christ's ministers are sent on, is the embassy of the Gospel of peace: their business is to declare that men by nature are enemies to God; that peace is made by the blood of Christ for such; by which means they are made useful to conciliate the minds of men to God's way of salvation and to bring them to submit to his government and laws: and when he adds, "in bonds", or "in a chain", he means, that he was in such circumstances, not for any crime, but for the Gospel, for which he was an ambassador; and therefore was not ashamed of his bonds, or chain, but rather gloried in them; and he makes mention of them to engage persons to a regard to him as an ambassador, and to his embassy; for an ambassador, especially an ambassador of Christ, that comes with his Gospel, and more especially that is suffering for it, ought to be received, heard, and honoured.
That therein I may speak boldly as I ought to speak; that is, the apostle beseeches the saints to pray for him, that since he was an ambassador for the Gospel, and in bonds, that he might speak in it, or rather of it boldly and freely; that he might have both liberty from his bonds, and liberty in his soul, and freedom of speech; and that he might use boldness in delivering his message, as became an ambassador of Jesus Christ.

For--Greek, as in Ephesians 6:19, "On behalf of which."
an ambassador in bonds--a paradox. Ambassadors were held inviolable by the law of nations, and could not, without outrage to every sacred right, be put in chains. Yet Christ's "ambassador is in a chain!" The Greek is singular. The Romans used to bind a prisoner to a soldier by a single chain, in a kind of free custody. So Acts 28:16, Acts 28:20, "I am bound with this chain." The term, "bonds" (plural), on the other hand, is used when the prisoner's hands or feet were bound together (Acts 26:29); compare Acts 12:6, where the plural marks the distinction. The singular is only used of the particular kind of custody described above; an undesigned coincidence [PALEY].

An ambassador in bonds - The ambassadors of men usually appear in great pomp. How differently does the ambassador of Christ appear!
