'Altar' in the Bible

I will wash my hands in innocence,And I will go about Your altar, O Lord,

Then I will go to the altar of God,To God, my exceeding joy;With the lyre I will praise You, O God, my God!

Then will You delight in the sacrifices of righteousness,In burnt offering and whole burnt offering;Then young bulls will be offered on Your altar.

The Lord is God, and He has given us light [illuminating us with His grace and freedom and joy].Bind the festival sacrifices with cords to the horns of the altar.
