Is there some verse in bible which explains the TRINITY?
It is not there in bible. But Qur’an says about TRINITY. Qura’an (Chapter 4 An-Nisa: 171) O People of the Book! Do not transgress the limits of your religion. Speak nothing but the Truth about Allah. The Messiah, Jesus, the son of Mary WAS NO MORE THAN A MESSENGER of Allah and His Word “Be” which He bestowed on Mary and a Spirit from Him which took the shape of a child in her womb. So believe in Allah and His Messengers and DO NOT SAY: “TRINITY”.” Stop saying that, it is better for you. Allah is only One Deity. He is far above from the need of having a son! To Him belongs all that is in the heavens and in the Earth.
