Isaiah 30:1

And that cover with a covering "Who ratify covenants" - Hebrews "Who pour out a libation." Sacrifice and libation were ceremonies constantly used, in ancient times by most nations in the ratifying of covenants: a libation therefore is used for a covenant, as in Greek the word σπονδη , for the same reason, stands for both. This seems to be the most easy explication of the Hebrew phrase, and it has the authority of the Septuagint, εποιησατε συνθηκας .
