'Partner' in the Bible

Whoever robs his father or his mother, and says, "It's not wrong." He is a partner with a destroyer.

As for Titus, he is my partner and fellow worker for you. As for our brothers, they are the apostles of the assemblies, the glory of Christ.

If then you count me a partner, receive him as you would receive me.

I John, your brother and partner with you in oppression, Kingdom, and perseverance in Christ Jesus, was on the isle that is called Patmos because of God's Word and the testimony of Jesus Christ.
