'Coat' in the Bible

The first one came out red-looking, covered with hair like a fur coat, and they named him Esau.

But you coat the truth with lies;you are all worthless doctors.

He wore cursing like his coat—let it enter his body like waterand go into his bones like oil.

Now when the wall has fallen, will you not be asked, ‘Where is the coat of whitewash that you put on it?’
