(based on Genesis 7—a story of creation)
Pair by pair Noah and Naomi, Shem and Varda, Ham and Ital, Japheth and Nitzan led the walking animals into their stalls or cages 14 clean (as in kosher to eat) animals of each species and 2 unclean (not so kosher) or two-by-two, depending on which part of the biblical narrative you're reading. The flyers found space to roost for themselves.
It had to be more than a little unnerving to escort the first predator across the gangplank. Do you push them? Do you pull them? How much force is too much? If you you tie a rope around their necks and pull, how much lead do you give yourself? Do you dare turn your back to them? Do you think they've eaten already?
