'Reliable' in the Bible

For the message is a witness to what is decreed; it gives reliable testimony about how matters will turn out. Even if the message is not fulfilled right away, wait patiently; for it will certainly come to pass -- it will not arrive late.

The one who says to wood, 'Wake up!' is as good as dead -- he who says to speechless stone, 'Awake!' Can it give reliable guidance? It is overlaid with gold and silver; it has no life's breath inside it.
