Surely God does not hear an empty cry

Elihu knows: “Surely God does not hear an empty cry, nor does the Almighty regard it.”
He had a good student in rabbi Jesus: “When you are praying, do not heap up empty phrases as the Gentiles do; for they think that they will be heard because of their many words. Do not be like them, for your Father knows what you need before you ask him. ” (Matthew 6:7-8)
