'Tell' in the Bible

Then said they unto him, Tell us, we pray thee, for whose cause this evil is upon us; What is thine occupation? and whence comest thou? what is thy country? and of what people art thou?

“Get up! Go to the great city of Nineveh and preach the message that I tell you.”

Who can tell if God will turn and repent, and turn away from his fierce anger, that we perish not?
