'Comrade' in the Bible

As for Titus, remember that he is a partner with me, and is my comrade in my labours for you. And as for our brethren, remember that they are delegates from the Churches, and are men in whom Christ is glorified.

Yet I deem it important to send Epaphroditus to you now--he is my brother and comrade both in labour and in arms, and is your messenger who has ministered to my needs.

and to our sister Apphia and our comrade Archippus--as well as to the Church in your house.

If therefore you regard me as a comrade, receive him as if he were I myself.
