The two most common quotes are:
Then God said, "Behold, I have given you every plant yielding seed that is on the surface of all the earth, and every tree which has fruit yielding seed; it shall be food for you." -Genesis 1:29
Then Daniel asked … ‘Let us be given vegetables to eat and water to drink.’ … At the end of ten days it was observed that they appeared better and fatter than all the young men who had been eating the royal rations.” -Daniel 1:8, 11–12, 15
The problem is there’s so much conflicting information in this book it’s impossible to make a convincing argument either way. There’s a huge debate on this very topic on YouTube, but ultimately it’s our conscience we have to live with, not the clucking tongues of our neighbors. I choose not to be the stuff of innocent animals’ nightmares.
