King James Version

Isaiah 6:10

Make the heart of this people fat, and make their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed.

James 5:19

Brethren, if any of you do err from the truth, and one convert him;

Apostolic Fathers

Shepherd of Hermas: Visions 1:3

But God is not angry with you on account of this, but that you may convert your house, which have committed iniquity against the Lord, and against you, their parents. And although you love your sons, yet did you not warn your house, but permitted them to be terribly corrupted. On this account is the Lord angry with you, but He will heal all the evils which have been done in your house. For, on account of their sins and iniquities, you have been destroyed by the affairs of this world. But now the mercy of the Lord has taken pity on you and your house, and will strengthen you, and establish you in His glory. Only be not easy-minded, but be of good courage and comfort your house. For as a smith hammers out his work, and accomplishes whatever he wishes, so shall righteous daily speech overcome all iniquity. Cease not therefore to admonish your sons; for I know that, if they will repent with all their heart, they will be enrolled in the Books of Life with the saints.” Having ended these words, she said to me, “Do you wish to hear me read?” I say to her, “Lady, I do.” “Listen then, and give ear to the glories of God.” And then I heard from her, magnificently and admirably, things which my memory could not retain. For all the words were terrible, such as man could not endure. The last words, however, I did remember; for they were useful to us, and gentle. “Lo, the God of powers, who by His invisible strong power and great wisdom has created the world, and by His glorious counsel has surrounded His creation with beauty, and by His strong word has fixed the heavens and laid the foundations of the earth upon the waters, and by His own wisdom and providence has created His holy church, which He has blessed, lo! He removes the heavens and the mountains, the hills and the seas, and all things become plain to His elect, that He may bestow on them the blessing which He has promised them, with much glory and joy, if only they shall keep the commandments of God which they have received in great faith.”

OT Pseudepigrapha

Odes of Solomon 10:3

To convert the souls of them who are willing to come to Him; and to lead captive a good captivity for freedom.
