'Participation' in the Bible

Be not diversely yoked with unbelievers; for what participation is there between righteousness and lawlessness? or what fellowship of light with darkness?

Where can harmony between Christ and Belial be found? Or what participation has a believer with an unbeliever?

begging us with much urging for the favor of participation in the support of the saints,

Through the proven character of this service [they will] glorify God because of the submission of your confession to the gospel of Christ and the generosity of [your] participation toward them and toward everyone,

The grace of the Lord Jesus Christ and the love of God, and the fellowship of the Holy Spirit be with you all.
