'Altar' in the Bible

I wash my hands in innocenceand go around Your altar, Lord,

Then I will come to the altar of God,to God, my greatest joy.I will praise You with the lyre,God, my God.

Then You will delight in righteous sacrifices,whole burnt offerings;then bulls will be offered on Your altar.

The Lord is God and has given us light.Bind the festival sacrifice with cordsto the horns of the altar.
