Isaiah 45:8 - Matthew Poole's English Annotations on the Holy Bible

Let the skies pour down righteousness; the righteous and gracious acts of God for his people shall be so many and illustrious, as if God rained down showers of righteousness out of heaven. Let the earth open; open itself, either to receive those showers of righteousness to be poured down from heaven, or to bring forth those fruits which might be expected from such showers. Let them, the heavens and the earth conspiring together, bring forth salvation; the redemption of God's people. Let righteousness spring up together; together with salvation. Whereas persons or people are sometimes delivered from their troubles by unjust courses, this shall be effected with righteousness, both on God's part, who will hereby assert his own justice and faithfulness to his people; and on Cyrus's part, who will do a most righteous and worthy action in rescuing a righteous and oppressed nation from cruel tyrants and oppressors. I the Lord have created it; this great work of salvation, and righteousness; whereof, though Cyrus is the instrument, I am the chief author.
