Did you ever noticed that donkeys all have a black band that goes from their neck down their back and crosses over their shoulders ? It's becaue when God, aka: Jesus, The Son etc., arrived in Jerusalem, he was sitting on a donkey. As a reward for having carried God on their back, all donkeys now have a cross on their back !
When I was little , a farmer who had donkeys told me that story... I never forgot it and he was right in one way for sure, all donkeys do have a black cross on their bakcs !
I love this image, look at those little guys... so sweet.
