Mark 11:2
Saying to them, go to the village ahead of you, and just as you enter it, you will find a colt tied there, which no one has ever ridden. Untie it and bring it here — the specific knowledge of the colt's location (which no one has ever ridden) communicates divine foreknowledge. A colt that has never been ridden is the appropriate vehicle for a sacred purpose — Numbers 19:2 and Deuteronomy 21:3 both specify an unused animal for sacred use. The instruction to untie and bring it is the operative commission.
