Are all 3 digit numbers in New Testament Triangles or Squares?

There is a claim circulating that all the three digit numbers in the New Testament are triangular numbers. This is commonly taken to be miraculous. As it turns out there is one three digit number in the New Testament that is not a triangle, it is a square. I put together a crude estimate that the chance of these five numbers being either triangles or squares by chance is about one in 55 thousand. So perhaps the choice of these numbers was miraculous.

What is a triangle number

But what is a triangular number? A triangular number is like a square number. Four is a square because if you count up all the dots in a 2 by 2 square you get four. Nine is square because if you count the dots in a 3 by 3 square you get nine.

A triangular number is based on the dots arranged in an equilateral triangle. An equilateral triangle with 2 dots on a side has 3 dots, 3 dots on a side has 6 dots, 4 dots on a side has 10 dots, like the ten pins in bowling.

The crude way of calculating these numbers is simply to add the whole numbers 1, 2, and so on until you reach the triangle root. The triangle root of 10 is 4. Add the numbers 1 to 4, 1+2+3+4, and the sum is 10.

A more sophisticated formula is square the root and then add the root. Then divide the sum by 2. (Root squared + root)/2=the triangle of the root.

This can also be written as the root plus one times the root divided by 2. ((r+1)*r)/2=the triangle of r, where r is the root.

Three digit triangles in the New Testament

The claim is that there are four three digit numbers in the New Testament and all are triangles. The first is in John 21:111. After his resurrection Jesus meets the apostles when they are fishing. The apostles catch 153 fish. 153 is the triangle of 17.

The second is in Acts 1:15. When a replacement for Judas was chosen there were 120 people in the congregation. 120 is the triangle of 15.

The third is in Acts 27:37. There were 276 people on Paul's ship when it was wrecked on Malta. 276 ins the triangle of 23.

The fourth and final one is Revelations 13:18, the infamous number of the beast 666. 666 is the triangle of 36.

But there is another three digit number

In Revelations 21:17 there is another three digit number. An angel measures the wall of the heavenly city and we learn it is 144 cubits high. 144 is three digits and it is not a triangle, it is however the square of 12. So there are five three digit numbers and they are all either triangles or squares.

Round numbers and estimates.

There are other three digit numbers that we might reasonably regard as round numbers or estimates. In John 21:7 we are told that the apostles boat was about 200 cubits from the shore.

It is reasonable to say this was an estimate, not an exact number, for several reasons. First, literal translations say it was an estimate. Second the boat was moving, and there were no doubt small waves on the shore, so an exact number would have been impossible to measure. Furthermore, no doubt, no one measured the distance between the boat and the shore. And finally it is a round number, round numbers are frequently, perhaps even normally estimates.

There are other verses in the New Testament where they use three digit numbers that might reasonably be called estimates. The word hundredfold is used five times, and the word hundreds is used once, Mark 6:40. The word hundreds is clearly not exact, they do not tell us how many hundreds.

The word hundredfold could be interpreted as being not exact, it is a round number and round numbers are often estimates. On the other hand if it is considered exact, it is a square number. This would give us six three digit numbers that are either squares or triangles.

But setting a hundredfold aside, at this point we can say there are five numbers that may be intended to be exact numbers and they are all triangles or squares. There maybe other numbers that I have missed. If you find them please contact me and pass on the information.

How unusual is this?

For those who do not want to wade into the math, I have calculated that the probability of these five three digit numbers all being either squares or triangular numbers is roughly one in 55 thousand.

How did I get this rough estimate? I used the roots. Let's start with a simple example.

If we are looking for triangle numbers in the area of 666, then about one out of 36 numbers is a triangle. The next triangle number that is lower than 666 is 630, which is 36 less, the next triangle number that is higher is 703, which is 37 more.

So if we just had four triangular numbers we could multiply their roots together to get a ball park estimate of the probability of the four numbers all being triangles. The four triangle roots are 17, 15, 23, and 36. If we multiply the together we get 211,110. So there is would be about one chance in 200 thousand that the four numbers were all triangles, if all three digit numbers were triangles.

Triangles and Squares

But there are five three digit numbers, not four and one is a square, which makes things much more difficult.

Once again to get a rough estimate I looked at the roots. I took the four triangle roots and the one square root and put them in a spread sheet. Then I looked at the closest square to each of the triangular numbers and the closest triangle to the square. I took the root of this number that was closest.

Then I divided 1 by each of the roots. Then I added the two fractions for each number. For example the triangle root of 666 is 36 and the closest square to 666 is 676. The square root of 676 is 26. So I divided one by both 36 and 26 and then added the two fractions together. This told me roughly what the chances were that 666 was either a square of a triangle.

Then I multiplied this fraction for each of the five three digit numbers together and the result was about 55 thousand.

The result is that the chance of seeing this pattern is about one in a 55 thousand. That is a pretty big number.

Of course your chance of seeing an interesting pattern of some sort if you are looking for interesting patterns is much higher than that.

Still I find this quite impressive, especially when you combine it with some of the other strange things I have found.

Did the Apostles Cooperate to Create this

These three digit numbers are found in three books, the Gospel of John, Acts, and Revelations. These books are attributed to two authors John and Luke. So no one person could have created the pattern without cooperation.

John and Luke, however, did not write the whole of the New Testament. Other works in the New Testament were attributed to Matthew, Mark, Paul, Peter, and Jude. So we might note that any of them could have potentially messed up the pattern by including a three digit number which was not a square or a triangle. So the cooperation of these other writers might have be required to create the pattern.

Of course, the books of the Bible were not finally chosen until centuries after they were written. The writers did not know their books would be included in a Bible. Furthermore, it seems unlikely that those church leaders who chose the books knew anything about the pattern. All of this would make it difficult for early church leaders to intentionally set up something like this.

So a miraculous explination seems reasonable.


The three digit triangle and square pattern is not the only time I have found interesting patterns in the Bible. A typology pattern I found greatly impressed several top experts. That pattern involved Old and New Testament figures who share the same name. The Old Testament stories foreshadow the New in miraculous ways.

This impressed a distinguished professor at the Graduate Theological Union in Berkeley, Wilhelm Wuellner and Gerry Matatics, a friend of Scott Hahn who tried to prevent him from joining the Catholic Church and ended up joining himself.

Finally, I have a index page with links that lead to many essays providing evidence and defense for the faith.
