In myth crows are the carriers of the soul and fly between the Earth plains, up and down, between Heaven & Hell. In both cases they fly over Heaven or over Hell and drop the souls to deliver.Further they are also omens for the souls who are cursed. They attracted by the soul en masse, that cares a curse, to bring it towards the next world and because it is such a heavy load, they will need many of them.
As last they are omens of bad things to happen.
In several countries it did rain crows as omen of a disaster coming to life.
This rain is caused, when 2 flocks of crows go into battle and each single one die till the last one and all drop out of the sky.
For the Lamb they are personal messengers and every time there is a grunge against the Lamb, crows are stationed to wait for the souls of enemies of the Lamb to bring them to Hell.
The promise that was made to them in the end, is that they are allowed to take place to the banquette of the Lamb, where all bad souls are served and allowed to be eaten by the crows, which will make their color from black into white, so they in pureness can go to Heaven.
