'Demanding' in the Bible

The Pharisees arrived and began arguing with Jesus. They tested him by demanding from him a sign from heaven.

But they kept pressing him with loud shouts, demanding that Jesus be crucified, and their shouts began to prevail.

What, then, is my reward? It is to be able to preach the gospel free of charge, and so I never resort to demanding my rights when I'm preaching the gospel.
