In Philippians 2:17 (NAB), Saint Paul says "But, even if I am poured out as a libation upon the sacrificial service of your faith, I rejoice and share my joy with all of you." The commentary of the United States Conference of Catholic Bishops upon this verse says "Libation: in ancient religious ritual, the pouring out on the ground of a liquid offering as a sacrifice. Paul means that he may be facing death."
