You're not good at being slippery. The issue isn't simply that the Jews were to be informed first. That is true. The issue, more precisely, is that they were the ONLY ones being informed at that time, to the EXCLUSION of everyone else. The children came first.
And guess what?
It was all according to plan, just as Christ said.
List them please. Let's examine them one at a time.
the sense of 'first' in Paul is mission strategy. It was to get them as preachers in to the mission. See the middle of Rom 10 through 11. 11 is about goading or urging them into the mission, not about a restored theocracy. Same sentiment as Acts 26:29. The theocracy and worship system was dismissed earlier in 26 at 6-8.
