This is a good, simple, and informative presentation. I love Biblical Scholarship when it involves etymology and historical context. This is a good example.

Where I see some insight further is in the context of the solar equinox beginning on the 21st and 3 days of the Sun's death and the rising of the Sun on the 25th of December where the days become noticeably longer. Hence I refer back to the death of Horus by Set on the 21st. We get our word for hour from Horus as well as the horizon. We also get our term for sunset from Set killing Horus in the myth from Egypt.

It's a good short listen and visual presentation. It could have been done in a better presentation but the information is more important and can be gathered.

And Merry Christmas!
