'Cowardly' in the Bible

But he said to them, "Why are you cowardly, you people of little faith?" Then he got up and rebuked the winds and the sea, and it was dead calm.

And he said to them, "Why are you cowardly? Do you still not have faith?"

And He said to them, “Go and tell that fox [that sly, cowardly man], ‘Listen carefully: I cast out demons and perform healings today and tomorrow, and on the third day I reach My goal.’

Peace I leave with you; My [perfect] peace I give to you; not as the world gives do I give to you. Do not let your heart be troubled, nor let it be afraid. [Let My perfect peace calm you in every circumstance and give you courage and strength for every challenge.]

But people who are cowardly, unfaithful, detestable, murderers, sexually immoral, sorcerers, idolaters, and all liars will find themselves in the lake that burns with fire and sulfur. This is the second death."
