The Jews reproved for their reliance on Egypt, Isa 30:1-7. Threatened for their obstinate adherence to this alliance, Isa 30:8-17. Images the most elegant and lofty, by which the intense gloriousness of Messiah's reign at the period when all Israel shall be added to the Church is beautifully set forth, Isa 30:18-26. Dreadful fall of Sennacherib's army, an event most manifestly typical of the terrible and sudden overthrow of Antichrist; as, unless this typical reference be admitted, no possible connection can be imagined between the stupendous events which took place in Hezekiah's reign, and the very remote and inconceivably more glorious displays of Divine vengeance and mercy in the days of the Messiah, Isa 30:27-33.
Verse 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.
