You would not need vaccines and such if you followed simple logical science. However, if you understand these scriptures I'm posting you also need to understand their environment. They didn't live in cities like New York. They were more spread out so each family could have farm land. Only the Levites lived in cities and maybe, at some point, some of the tribe of Judah if they were wealthy. If you're not wealthy you had a greater tendency to live in the country. And if you weren't as rich as Abraham who had many servants, you still weren't breathing in recirculated air. They lived in tents. So logically, people in cities are in more danger when it comes to viruses.
If you lived in the country where it took days to travel, the likelihood of someone coming to your tent, not knowing they were sick, was less likely. And they knew what animals they could eat safely and they knew not eat sick animals.
And we know what happens when you don't correctly prepare raw meats. Who among us doesn't know about the danger of salmonella in raw chicken? No agent in the world could convince us that salmonella doesn't exist. So why is an agent trying to convince us that animals can't pass viruses to humans? If they can pass us bad bacteria then they can pass us viruses as well. Viruses aren't special or human only. salmonella is also highly contagious. Kissing someone with salmonella is enough to catch it yourself. So why is an agent here, pretending that viruses like covid-19 don't exist and trying to use the bible as some kind of evidence? THE BIBLE SAYS THE OPPOSITE!
So if you live in a city where you cannot avoid sick people then yeah... maybe you need to think about getting a vaccine to teach your body how to fight the virus. That's what vaccines do. But if you don't live in a highly congested area and your exposure can be minimized by keeping your distance from strangers then I don't think everyone needs to be vaccinated. Not saying the virus cant still get to you, but it wont have as many opportunities and attempts like it would in the city.
Ye shall therefore put difference between clean beasts and unclean, and between unclean fowls and clean: and ye shall not make your souls abominable by beast, or by fowl, or by any manner of living thing that creepeth on the ground, which I have separated from you as unclean.
This is specifically to guard against infectious diseases and bacteria:
All the days that he separateth himself unto the Lord he shall come at no dead body.
And the priest shall look on the plague in the skin of the flesh: and when the hair in the plague is turned white, and the plague in sight be deeper than the skin of his flesh, it is a plague of leprosy: and the priest shall look on him, and pronounce him unclean.
And whosoever beareth ought of the carcase of them shall wash his clothes, and be unclean until the even.
And upon whatsoever any of them, when they are dead, doth fall, it shall be unclean; whether it be any vessel of wood, or raiment, or skin, or sack, whatsoever vessel it be, wherein any work is done, it must be put into water, and it shall be unclean until the even; so it shall be cleansed.
And whosoever toucheth his bed shall wash his clothes, and bathe himself in water, and be unclean until the even.
And whomsoever he toucheth that hath the issue, and hath not rinsed his hands in water, he shall wash his clothes, and bathe himself in water, and be unclean until the even.
And if any man's seed of copulation go out from him, then he shall wash all his flesh in water, and be unclean until the even.
And if a woman have an issue, and her issue in her flesh be blood, she shall be put apart seven days: and whosoever toucheth her shall be unclean until the even.
This is specifically a command to have a lockdown where the Israelites were not free to leave their homes:
And ye shall take a bunch of hyssop, and dip it in the blood that is in the bason, and strike the lintel and the two side posts with the blood that is in the bason; and none of you shall go out at the door of his house until the morning.
4 If the bright spot be white in the skin of his flesh, and in sight be not deeper than the skin, and the hair thereof be not turned white; then the priest shall shut up him that hath the plague seven days:
5 And the priest shall look on him the seventh day: and, behold, if the plague in his sight be at a stay, and the plague spread not in the skin; then the priest shall shut him up seven days more:
Yes... folks... that's Quarantine. If you have covid it's 2 weeks. Same strategy. AND BOUT THE SAME number of days as covid quarantine because of the virus's incubation period!!! So wear a mask and wash your hands. And know that the people in ancient times had to do the same d-mn thing for the same d-mn reasons. This is not rocket science. It's in the bible.
