JOSHUA 8-9:
Yesterday the walls of Jericho “came a-tumbling down” after some skillful trumpet playing while marching around the city for 7 days. The city was devoted to destruction, meaning that this was God's judgement upon them, and that everything was to be destroyed. Right after this amazing victory, Israel learned through a man named Achan that keeping treasures devoted to destruction makes oneself devoted to destruction.

PSALM 70:
David pleads in this psalm for help against his enemies. And this poem is a repetition of the last part of Psalm 40.

ACTS 21b:
Paul, Luke, and the other companions arrived in Jerusalem. On the way, Paul heard the prophecies that he should not go to Jerusalem. Once there, he received advice from James and the others which turned out to be disastrous in the end. Should Paul have followed the advice he was given by prophecy? My opinion is that he did the will of God which had already been revealed to him before those prophecies. In other words, the information in those prophecies that Paul would be arrested and beaten was from God. The interpretation that Paul should not go there was added by people, and Paul was right in not following their advice.

NLT Translation notes:
Ps. 70:2 May those who [are trying//try] to kill me be humiliated and put to shame. May those who take delight in my trouble be turned back in disgrace.
5 But as for me [now], I am poor and needy; please hurry to my aid, O God. You are my helper and my savior; O  Lord , do not delay.
