Be still

Help! Ever since I read Liz's post about the hymn Be Still, I have had lyrics in my head and I can't remember where they came from. I have the tune and lyrics to this hymn but can't remember where I learnt it!!

The lyrics are:
Be still in the presence of the Lord, the Holy one is here,
Stand ___ before him now, in reverence and fear,
In him no sin is found,
We are on holy ground (??)
etc

And then I get stuck. It's a lovely hymn, but I can't remember the rest of the words - can anyone help me???
