Lifting Hands to God

I recently heard a friend of mine say that lifting hands to God is not commanded anywhere in the Bible. When I heard him say that I was surprised because (a) he is a man of the Word, and so I assumed he knew what he was talking about and (b) I was pretty sure that it was commanded in the Bible.

"Come, bless the Lord, all you servants fo the Lord,
who stand by night in the house of the LORD!
Lift up your hands to the holy place
and bless the LORD!" - Psalm 134.1-2

There are others also.
