The key numbers in the Bible are 12, 7, 6 and 40. Think of all the places 12, 7 and 6 appear in our culture. Then think about 40. Moses wandered for 40 years. Forty appears to be of importance in the Torah number scheme but in few other places. Or maybe it disguises itself as 4?
Forty seems to appear more often as four in actual existing culture whereas sixty seems to appear more often as six in the Torah.
There are 24 hours in a day, 24 = 6 x 4, four quarters of the globe and four seasons in a year. These are all arbitrary. Someone at some time chose these concepts that we use on a daily basis. We organize our lives around the seven day week. The religious will say it is because God created the world in 7 days. If you read the first Genesis passages carefully, you will note this is incorrect. It was “created” in 6 days plus 1 day for rest. 6 + 1 = 7. A very basic equation. Let me re-write that: 61.
Now 7 has become 61 and we may still not be seeing it completely. What is 61? You know this.
