There is already an existing question (Reference) that asks about the ‘angel’ that Stephen says spoke with Moses on Mt Sinai. The accepted answer included....

“The angel of the Lord that Stephen talks about is the same being that spoke to Moses in the Old Testament and guided Israel through the wilderness.”

However, further on in Acts 7 we read ...

ACTS 7:53* who have received the law by the direction of angels and have not kept it.”

And Strongs under the outline for [Greek] ‘diatagē’ / translated ‘direction’ in the NKJ above includes ..... “influenced by the authority of the ordaining angels,”

This leads me to consider that ‘angels’ may have had more to do with the giving of the Law than just the ‘one’ representing God. (Inference taken from the accepted answer referenced above).

So my question is asking for a more detailed outline of the role of the angels in this incident on Mt Sinai, one that satisfies v53.
