What is the significance to the number 3 in the Bible? There is already a question about the number seven, but no one said anything about 3.

Here are a few 3's I came up with:

• The Trinity (Godhead) is 3 in one
• Peter denies knowing Jesus 3 times and later says he loves him 3 times
• Jesus rose on the 3rd day
• Both 777 and 666 consist of 3 digits
• "holy, holy, holy" is the Lord God Almighty (Isaiah 6:3 and Revelation 4:8)

There are probably more that I can't think of right now. I just looked up 777 and it's not even in the Bible, so I don't know where that came from but I heard it somehow represents God.

So what is the significance to the number 3?
