'Trial' in the Bible

The Pharisees followed Him and began to dispute with Him, asking Him for a sign in the sky, to make trial of Him.

Shall we give, or shall we not give? But he, knowing their hypocrisy, said unto them, Why make ye trial of me? bring me a denarius, that I may see it.

When they take you away and hand you over for trial, don't worry ahead of time about what you will say. Instead, say whatever is given to you at that time, because it won't be you speaking, but the Holy Spirit.
