'Behalf' in the Bible

by whom we have received grace and apostleship in behalf of his name, for obedience of faith among all the nations,

For we do not again commend ourselves to you, but we are giving to you occasion of boast in our behalf, that ye may have such with those boasting in countenance, and not in heart.

Whether as regards Titus, he is my companion and fellow-labourer in your behalf; or our brethren, they are deputed messengers of assemblies, Christ's glory.
