1 Corinthians 1:10-12

10 Now I beseech you, brethren, by the name of our Lord Jesus Christ, that ye all speak the same thing and [that] there be no divisions among you, but [that] ye be perfect, joined together in the same understanding and in the same perception.

11 For it has been declared unto me of you, my brethren, by those [of the house] of Chloe, that there are contentions among you.

12 In other words, that each one of you says, I am of Paul, and I of Apollos, and I of Cephas, and I of Christ.
