Then will I go unto the altar of God, unto God my exceeding joy: yea, upon the harp will I praise thee, O God my God.

Then shalt thou be pleased with the sacrifices of righteousness, with burnt offering and whole burnt offering: then shall they offer bullocks upon thine altar.

Even the sparrow found a house for herself and the swallow a nest to lay her young at your altar, LORD of the Heavenly Armies, my king and God.

God is the LORD, which hath shewed us light: bind the sacrifice with cords, even unto the horns of the altar.
