Each of the holidays mentioned in Numbers 28-29 are just recaps of previous holidays that God has been talking about since Exodus, with particular emphasis on the animal-sacrifices portions of the “festivities.” That alone should give you an idea of the character of God.
Numbers 29:12-40 talks about Sukkot, which Christians call the Feast of the Tabernacles. I find it interesting that the Christian publications I read never seem to refer to any of the traditional Jewish terms by their traditional Hebrew names. I wonder if this is done to purposely distance themselves from their Jewish heritage and whitewash their religion?
Anyway, although God has been talking about Sukkot for several years, which means that the Israelites have probably celebrated it several times, but it isn’t until now that God finally explains the proper celebration protocol, i.e., the animal butchering. And if you thought Passover was gruesome, Sukkot will make you lose your lunch. The first day begins with the painful and bloody execution of 13 young bulls, 2 rams, 14 lambs, and a goat. On the second day you must kill 12 young bulls, and the same number of rams, lambs, and goats. This continues for the whole week, each day decreasing the number of bulls, while keeping the rest the same. Finally, on the eighth day, there is a final sacrifice of a bull, a ram, 7 lambs, and a goat. To sum up this “holiday,” God has demanded the death of an additional 71 bulls, 15 rams, 105 lambs, and 8 goats; a total of 199 animals!
This gives us a final count of 1,215 animal-sacrifices each year! But before you scrunch up your nose in disgust, remember that this is the absolute bare minimum! Every time someone sins, more dead animals; every time a woman has a heavy flow, more dead animals; hell, even when something really good happens to someone, more dead animals! This is a religion of death.
