32 All the believers were one in heart and mind. No one claimed that any of their possessions was their own, but they shared everything they had. 33 With great power the apostles continued to testify to the resurrection of the Lord Jesus. And God’s grace was so powerfully at work in them all 34 that there were no needy persons among them. For from time to time those who owned land or houses sold them, brought the money from the sales 35 and put it at the apostles’ feet, and it was distributed to anyone who had need.
36 Joseph, a Levite from Cyprus, whom the apostles called Barnabas (which means “son of encouragement”), 37 sold a field he owned and brought the money and put it at the apostles’ feet. ...
5 Now a man named Ananias, together with his wife Sapphira, also sold a piece of property. 2 With his wife’s full knowledge he kept back part of the money for himself, but brought the rest and put it at the apostles’ feet.
I have not found this expression in other biblical texts. A situation where someone puts something at someone else's feet. I would like to know what the exact meaning of this expression is.
Does this just mean that the apostles are responsible for the money? or does "put at the feet" imply some kind of devotion? Or a mark of respect? A hierarchical relationship? Something else ?
Why did the writer include this detail which he considers important since it is mentioned no less than three times in a row in this specific episode and he is the only one to have used this expression.
