this is what James was doing, even what was prophesied in the very same chapter:
And as we stayed many days, a certain prophet named Agabus came down from Judea. When he had come to us, he took Paul’s belt, bound his own hands and feet, and said, “Thus says the Holy Spirit, ‘So shall the Jews at Jerusalem bind the man who owns this belt, and deliver him into the hands of the Gentiles.’ ”
(Acts 21:10-11)
notice who the Spirit of Prophecy said would bind Paul: the Jews.
notice how: with his own belt, hands and feet.
read on:
the people ran together, seized Paul, and dragged him out of the temple; and immediately the doors were shut. Now as they were seeking to kill him, news came to the commander of the garrison that all Jerusalem was in an uproar. He immediately took soldiers and centurions, and ran down to them. And when they saw the commander and the soldiers, they stopped beating Paul. Then the commander came near and took him, and commanded him to be bound with two chains; and he asked who he was and what he had done.
(Acts 21:30-33)
notice that the Jews did not physically bind Paul hand and foot.
the Romans did. with chains, not with Paul's belt.
Paul was not physically bound until the commander of the garrison came and ordered his soldiers to do so.
so the binding Paul was to be subjected to that the LORD God spoke through Agabus was not the shackling of his hands and feet by physical fetters.
the binding that God determined Paul to experience was something the Jews did to Paul.
consider James, the Jew, speaking to Paul on behalf of the believing Pharisees.
consider what was Paul's belt. consider how his hands and feet were restricted. consider how they delivered Paul.
maybe if i keep pointing this out to you one day you will comprehend it
