Adonai instructed the Israelites to find a pure, undefiled parah adumah, red heifer, and bring it to Eleazar the priest. Unlike other sacrifices where a male animal was offered, the slaughter for the purification water was female. A heifer is a young cow that has never birthed a calf. The animal’s hair was to be entirely of one color: red. However, the word adumah and adamah (earth) have the same root so the color is more brownish red like the earth than bright red like a rose. Its hair was to be straight to ensure that the heifer had never worn a yoke.
"Your eyes will see Jerusalem: A tent which will not be folded; its stakes will never be pulled up" (Isaiah 33:20).
