Revelation 21:13 in the King James Version (KJV) of the Bible reads, "On the east three gates; on the north three gates; on the south three gates; and on the west three gates." This verse is part of the final book of the New Testament, often referred to as the Book of Revelation or the Apocalypse of John, and is attributed to the Apostle John.

The Book of Revelation is known for its apocalyptic imagery and symbolism, and it is considered by many to be a highly symbolic and metaphorical work. It is also a deeply theological text, dealing with themes of divine judgment, the end times, and the ultimate triumph of good over evil.

In the larger context of Revelation 21, the chapter describes the vision of a new heaven and a new earth, as well as the New Jerusalem, which is described as a city of gold, precious stones, and pearls. This city is depicted as coming down from heaven and being adorned with the glory of God. The verse 13, which mentions the gates on each side of the city, is part of the description of the city's layout.

The imagery of gates in this verse can be seen as symbolic of access and entrance. In ancient times, gates were the points of entry and exit for cities, and they symbolized control and authority. In the context of the New Jerusalem, the gates can be seen as representing the access points to the city, and by extension, the access to the presence of God and the blessings of the new heaven and earth. This ties in with the larger theme of divine salvation and redemption that runs throughout the Book of Revelation.

The number three is also significant in this verse, as it is repeated four times. In biblical numerology, the number three is often associated with divine perfection and completeness. This repeated use of the number three can be seen as emphasizing the completeness and perfection of the city of God. The symmetry and balance of having three gates on each side signifies the harmony and fullness of the New Jerusalem.

Furthermore, the mention of the directions (east, north, south, and west) also carries symbolic significance. In biblical and ancient Near Eastern cultures, these directions were often associated with various meanings and connotations. For example, the east was often associated with the rising sun and divine blessings, while the west was associated with darkness and death. The inclusion of gates on all sides of the city could be interpreted as a symbol of inclusivity and accessibility, suggesting that the blessings and promises of the new heaven and earth are available to people from all directions and walks of life.

In sum, Revelation 21:13 is a rich and evocative verse that is deeply symbolic and laden with meaning. It speaks to the themes of divine perfection, completeness, access to the presence of God, and the inclusivity of divine blessings. It is part of the larger vision of the New Jerusalem and the new heaven and earth, and it serves as a powerful symbol of hope and redemption for believers. The verse reflects the rich and complex theology of the Book of Revelation and invites readers to contemplate the ultimate triumph of good over evil and the fulfillment of God's promises.
