First Washing, Then Worship

Through Him then let us continually offer up a sacrifice of praise to God, that is, the fruit of lips that acknowledge His name. - Hebrews 13:15

The words translated “sacrifice of praise” occur in the LXX of Leviticus 7:12 and speak of the highest form of peace offering under the old covenant. This thank offering was  voluntary offering and could only be made after the expiatory offerings had been presented and the worshiper was ritually clean; it’s primary purpose was to express gratitude to God.
