Where was the trinity revealed?

The Trinity was revealed in various parts of The Bible, but a key moment is during the baptism of Jesus, as described in the Gospels. At this event, the Father’s voice is heard from heaven, the Holy Spirit descends like a dove, and Jesus is present in the water, illustrating the three persons of the Trinity. Additionally, the Great Commission in Matthew 28:19 commands baptizing in the name of the Father, the Son, and the Holy Spirit, further emphasizing the concept of the Trinity.
