'Red' in the Bible

He answered them: “When evening comes you say, ‘It will be good weather because the sky is red.’

And in the morning, ‘Today will be stormy because the sky is red and threatening.’ You know how to read the appearance of the sky, but you can’t read the signs of the times.

This man led them out and performed wonders and signs in the land of Egypt, at the Red Sea, and in the wilderness 40 years.

By faith they crossed the Red Sea as though they were on dry land. When the Egyptians attempted to do this, they were drowned.

Then another horse went out, a fiery red one, and its horseman was empowered to take peace from the earth, so that people would slaughter one another. And a large sword was given to him.

This is how I saw the horses in my vision: The horsemen had breastplates that were fiery red, hyacinth blue, and sulfur yellow. The heads of the horses were like lions’ heads, and from their mouths came fire, smoke, and sulfur.

Then another sign appeared in heaven: There was a great fiery red dragon having seven heads and 10 horns, and on his heads were seven diadems.
