The Bible verse Revelation 16:5 from the King James Version (KJV) reads: "And I heard the angel of the waters say, Thou art righteous, O Lord, which art, and wast, and shalt be, because thou hast judged thus."

This verse is part of the book of Revelation, which was written by the apostle John while he was exiled on the Greek island of Patmos. The book is filled with vivid and symbolic imagery and is often interpreted as a prophetic vision of the end times.

In Revelation 16:5, the angel of the waters is speaking to God, acknowledging His righteousness and authority in judgment. The repetition of "which art, and wast, and shalt be" emphasizes the eternal and unchanging nature of God. This declaration of God's righteousness and permanence sets the stage for the following verses, which describe the outpouring of God's judgment on the earth.

The theme of judgment is a central focus of the book of Revelation, and it is often seen as a polarizing and controversial topic. Some view it as a message of warning and hope, while others see it as a source of fear and uncertainty. However, in the context of Revelation 16:5, the emphasis is on the righteousness of God's judgment. The angel of the waters is acknowledging that God's judgment is fair and just, and that He is the ultimate authority over all creation.

The symbolism of the "angel of the waters" in this verse is also significant. Throughout the Bible, water is often used as a symbol of purification, cleansing, and renewal. In this context, the angel of the waters represents a spiritual being who has authority over the natural element of water, and who is testifying to the righteousness of God's judgment. This imagery serves to reinforce the idea that God's judgment is not arbitrary or capricious, but is rooted in His divine wisdom and justice.

Furthermore, the declaration "Thou art righteous, O Lord" serves as a reminder that God's judgment is rooted in His character. The righteousness of God is a recurring theme in the Bible, and it speaks to His perfect moral and ethical nature. This verse affirms that God's judgment is not motivated by human emotions or biases, but is grounded in His holiness and goodness.

In a broader theological context, Revelation 16:5 can also be seen as a affirmation of God's sovereignty. The acknowledgment of God's eternal nature - "which art, and wast, and shalt be" - reinforces the idea that He is the ultimate authority over all creation, and that His judgments are not subject to human opinions or interpretations.

In conclusion, Revelation 16:5 is a powerful declaration of God's righteousness and authority in judgment. The verse emphasizes the eternal nature of God, His moral perfection, and His sovereignty over the natural elements. This declaration sets the stage for the following verses, which describe the outpouring of God's judgment on the earth. In interpreting this verse, it is important to consider its theological and symbolic significance, and to recognize it as part of the larger narrative of the book of Revelation.
