'Behalf' in the Bible

Now I can find joy amid my sufferings for you, and I fill up in my own person whatever is lacking in Christ's afflictions on behalf of His Body, the Church.

For I would have you know in how severe a struggle I am engaged on behalf of you and the brethren in Laodicea and of all who have not known me personally,

Epaphras, who is one of yourselves, a bondservant of Jesus Christ, sends greetings to you, always wrestling on your behalf in his prayers, that you may stand firm--Christians of ripe character and of clear conviction as to everything which is God's will.
