what does the bible say?
The number 11:11 has no biblical meaning. Rather, the meanings associated with 11:11 are merely superstition and are rooted in numerology.
In numerology, the number 11 is considered a "Master Number" that signifies psychic awareness or spiritual intuition. When 11 is doubled to 11:11, it signifies even more power. Coming from a more New Age perspective, the number 11 is considered an "angel number," so seeing 11:11 is supposed to mean that angels are near. These sorts of associations can make people view 11:11 as a lucky number, even to the point of making a wish at the time 11:11. However, this idea of 11:11 having some sort of magical powers is not biblically founded in any way and is instead based in astrology, fortune-telling, and the occult.
Some will try to come up with hidden biblical meanings based on 11:11 chapters and verses in different books of the Bible. Not only does 11:11 have no special significance, when the Bible was written, there were no chapters and verses. There is no unique spiritual significance associated with the eleventh verse of the eleventh chapter in a book of the Bible. However, "All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness" (2 Timothy 3:16). So those verses certainly do hold significance, just not for mysterious reasons.
Also, it’s important to keep in mind that God is not a God of hiding; He is a God of light. He provides wisdom and reveals the truth even when it is hidden by darkness. Daniel 2:21–22 says: "He changes times and seasons; he removes kings and sets up kings; he gives wisdom to the wise and knowledge to those who have understanding; he reveals deep and hidden things; he knows what is in the darkness, and the light dwells with him."
