'Instrumentality' in the Bible

Then the whole assembly remained silent while they listened to the statement made by Paul and Barnabas as to all the signs and marvels that God had done among the Gentiles through their instrumentality.

seeing that He has appointed a day on which, before long, He will judge the world in righteousness, through the instrumentality of a man whom He has pre-destined to this work, and has made the fact certain to every one by raising Him from the dead."

God also brought about extraordinary miracles through Paul's instrumentality.

After exchanging friendly greetings, Paul told in detail all that God had done among the Gentiles through his instrumentality.

and all [of them] drank the same spiritual drink, for they were drinking from a spiritual rock which followed them; and the rock was Christ.

May you be abundantly enriched so as to show all liberality, such as through our instrumentality brings thanksgiving to God.

Why, then, the Law [what was its purpose]? It was added [after the promise to Abraham, to reveal to people their guilt] because of transgressions [that is, to make people conscious of the sinfulness of sin], and [the Law] was ordained through angels and delivered to Israel by the hand of a mediator [Moses, the mediator between God and Israel, to be in effect] until the Seed would come to whom the promise had been made.
