'Red' in the Bible
(Now the Amalekites and the Canaanites were living in the valleys.) Tomorrow, turn and journey into the wilderness by the way of the Red Sea."
"This is the ordinance of the law which the Lord has commanded: 'Instruct the Israelites to bring you a red heifer without blemish, which has no defect and has never carried a yoke.
"'Then a man who is ceremonially clean must gather up the ashes of the red heifer and put them in a ceremonially clean place outside the camp. They must be kept for the community of the Israelites for use in the water of purification -- it is a purification for sin.
Then they traveled from Mount Hor by the road to the Red Sea, to go around the land of Edom, but the people became impatient along the way.
