The Bible does not have a definitive statement about tattoos in the book of Revelation or anywhere else in the New Testament. However, Leviticus 19:28 says, "Do not cut your bodies for the dead or put tattoo marks on yourselves. I am the Lord". Some Christians interpret this verse as a prohibition against tattoos, while others argue that it refers to specific cultural practices in ancient times and is not applicable to modern tattooing.

Regarding the mention of Jesus having a name written on his thigh in Revelation 19:16, some people have interpreted this as a tattoo, but it is more likely to be symbolic. Jesus was Jewish and observant Jews living under the law knew that tattoos were taboo (Leviticus 19:28) . Jesus fulfilled the Mosaic law, He did not violate it.

In summary, while the Bible does not explicitly forbid tattoos, some Christians interpret Leviticus 19:28 as a prohibition against them. However, others argue that this verse refers to specific cultural practices in ancient times and is not applicable to modern tattooing. The mention of Jesus having a name written on his thigh in Revelation 19:16 is more likely to be symbolic than a tattoo. Ultimately, Christians should seek wisdom and guidance from God when making decisions about tattoos or any other aspect of their lives.
