<p>Nebuchadnezzar asked Ben Sira a question that most people wouldn't think to ask: why does an ox have no hair on its nose? The answer, according to the Alphabet of Ben Sira (c. 700-1000 CE), takes us all the way back to the conquest of the Land of Israel.</p>
<p>When Joshua led the Israelites in their march around the walls of Jericho, he had a problem. Joshua was a large man - the text says he was fat - and needed an animal to carry him during the siege. They tried a horse. It collapsed under his weight. They tried a donkey. Same result. A mule? Dead.</p>
<p>Finally, they brought him an ox. The ox carried him without complaint, circling the walls of Jericho day after day until those famous walls came tumbling down. Joshua was so grateful, so moved by this humble animal's strength and willingness, that he leaned down and kissed the ox right on the nose.</p>
<p>And that, Ben Sira explains, is why oxen have smooth, hairless noses to this day. The kiss of a righteous man left a permanent mark on the species. It's a wonderfully strange little origin story - the kind of folk explanation (etiological tale) that the Alphabet of Ben Sira specializes in. Behind the humor, there's a quiet lesson about gratitude: even a great military leader should honor the beast that carried him to victory.</p>
