Who am I?

Can you guess?

I walk in places where I am told

High up here, among crags and cliffs bold

My horns are many, my hooves sharp

I heart the shepherd and obey his flock

No guess by golly to be sure

In depths, I travel in truth and honesty

I divide according to laws divine

Touch not the oil, nor the wine

The grapes are near ready in time

Push, prod and protect

I keep the hearts, its innocence

Walking where he inclines

My lord, my shepherd

By his will 

All will be done
