'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 they all drank the same spiritual (supernaturally given) drink. For they drank from a spiritual Rock which followed them [produced by the sole power of God Himself without natural instrumentality], 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.
What then was the purpose of the Law? It was added [later on, after the promise, to disclose and expose to men their guilt] because of transgressions and [to make men more conscious of the sinfulness] of sin; and it was intended to be in effect until the Seed (the Descendant, the Heir) should come, to and concerning Whom the promise had been made. And it [the Law] was arranged and ordained and appointed through the instrumentality of angels [and was given] by the hand (in the person) of a go-between [Moses, an intermediary person between God and man].
