The rabbis preserved a strange little tradition about how Og, the giant king of Bashan, survived the Flood. The Torah never explains it. Og appears later, towering over the Israelites in the wilderness, and Moses himself has to fight him (Numbers 21:33). But how did he live through the waters that drowned every other creature outside the ark?
The Targum of Jonathan ben Uzziel says he clung to the outside of the ark itself. Noah, according to one tradition, drilled a small hole in the side of the teivah and passed food through it every day, feeding the giant like one feeds a stray from a window.
The Book of Jasher imagines Og’s feet forty miles long. Later storytellers, building on this, explained every impossible feat Og performed afterward: how he uprooted mountains, how he nearly crushed the Israelite camp with a boulder. If his feet were forty miles long, of course he could do such things.
What the tradition is really saying is that the old world never fully washes away. Giants, grudges, and unfinished business cling to the outside of every ark.
