Rainbow
New TestamentVine's Expository Dictionary of Biblical Words
Definition
whence Eng., "iris," the flower, describes the "rainbow" seen in the heavenly vision, "round about the throne, like an emerald to look upon," Rev 4:3, emblematic of the fact that, in the exercise of God's absolute sovereignty and perfect counsels, He will remember His covenant concerning the earth (Gen 1:9-17); in Rev 10:1, "the rainbow," RV, the definite article suggests a connection with the scene in Rev 4:3; here it rests upon the head of an angel who declares that "there shall be delay no longer" (Rev 4:6, RV marg., the actual meaning); the mercy to be shown to the earth must be preceded by the execution of Divine judgments upon the nations who defy God and His Christ. Cp. Eze 1:28.
