Only three people were allowed to ask God ANYTHING. They were Solomon (1Kings 3:5), Ahaz (Isaiah 7:11) and, of course, Jesus Christ (Psalm 2:9).
The three gifts given to Israel by God were his law, the land of their inheritance, and their calling (the world to come).
The Bible only mentions the name of three angels (Michael, Gabriel and Lucifer).
How is the number 3 related to SEX SINS?
There are three places in the New Testament where sex sins are specially referenced. The first is in Romans 1:20 - 32, where certain people who reject God are given over to defile themselves in a variety of ways that includes homosexuality (male and female) and overall sexual immorality.
The second mention of sex-related sins is in 1Corinthians 5:1 - 13, where the apostle Paul must handle the problem of the local church allowing a member to openly commit incest. The third sex issue dealt with in the New Testament is in Revelation 2:19 - 25. A female who considers herself a prophetess within the Thyatira church, in the spirit of Jezebel, was teaching believers to commit sexual immorality and spiritual adultery.
Three in Prophecy
Next to seven, 3 is the most commonly found or referenced number in Revelation. An angel is charged to cry three woe's to those who live on earth to warn them of more trials to come (Revelation 8:13). The murdered bodies of the Two Witnesses will not be allowed to be buried but rather will lie openly in Jerusalem for three days before they are resurrected. Three unclean spirits will be allowed to deceive the whole world to FIGHT the returning Jesus Christ in what is called the battle of Armageddon (Revelation 16:13 - 16). The new Jerusalem, created by God for placement on a new earth, will be shaped like a square with three gates on each side (Revelation 21:13).
Additional information on the Biblical Meaning of 3
God is described, in the very beginning of the book of Revelation, as a Being "which is, and which was, and which is to come" (Revelation 1:4). There are 3 great periods of God's annual Feast days of worship. They are the Spring festivals (Passover and Days of Unleavened Bread), the summer festival (Pentecost) and the Fall festivals (Feast of Trumpets, Atonement and Feast of Tabernacles).
