When I talk about 'angels', I am speaking about spirit-beings that Jehovah God created.
When I talk about 'sons' here, I am talking about these angelic spirit-beings that Jehovah created which are said to be myriads of them. These would include Michael, Satan, and Gabriel.
Did he create all of them at the same time... or in many septate groups at different times.
If it was many septate groups at different times, that means there is a group of however many they were, that are Jehovah's first angelic spirit-being sons. These unknown number of sons would be his firstborns/first created angelic spirit-being sons.
Now at this point, no matter how many more groups followed to complete all the myriads that were created, the one thing that would be so, is that the first group were on hand to witness ALL the following groups being created.
Now what if Jehovah didn't start with a group, what if he started with one, maybe just Michael.
Then that would mean Michael was his firstborn/first created angelic spirit-being son.
Then after that, what if he went to creating groups at a time until all angelic spirit-being sons were created.
That would mean that Michael his firstborn/first created angelic spirit-being son was on hand to see all other angelic spirit-being sons being created.
Now jumping to Jesus, with Jehovah calling him a 'son' (5207. huios) at Luke 9:35. That mention of him being called Jehovah's 'son' is no different than all the myriads of angelic spirit-beings being called Jehovah's 'sons'. (1121. ben - 5207. huios)
The significance when it comes to Jesus is that he was audibly/publicly called 'son' by Jehovah in order to be glorified by him. And it was said that he was the chosen one and to listen to him.
