'Hands' in the Bible

And labour, working with our own hands: being reviled, we bless; being persecuted, we suffer it:

If then there are questions to be judged in connection with the things of this life, why do you put them in the hands of those who have no position in the church?

Or again, is it only Barnabas and myself who are not at liberty to give up working with our hands?

Then comes the end, when He hands over the kingdom to God the Father, when He abolishes all rule and all authority and power.
