'Behalf' in the Bible

just as you learned [it] from Epaphras, our dear fellow slave who is a faithful minister of Christ [on] our behalf,

Now I rejoice in my sufferings on behalf of you, and I fill up in my flesh what is lacking of the afflictions of Christ, on behalf of his body which is the church,

For I want you to know how great a struggle I have on behalf of you, and those in Laodicea, and all those who have not seen my face {in person},

Epaphras, who is [one] of you, greets you, a slave of Christ always struggling on behalf of you in his prayers, that you may stand mature and fully assured in all the will of God.

For I testify to him that {he is working hard} on behalf of you and those in Laodicea and those in Hierapolis.
