The Chumash says that Yaval was "Avi Yoshev Ohel u'Mikneh", which Rashi explains to be the first one to shepherd cattle and take them from place to place (here for a month, there for a month) to graze.<div><br>
</div><div>But Hevel was a shepherd before Yaval, so what was Yaval's chiddush?</div><div><br></div><div>Two possibilities I thought of:</div><div>1) He was the first to shepherd cattle, as opposed to sheep. I don't really like this answer, because is that really such a vastly different thing?</div>
<div>2) He was the first to move his home with the animals as they finished grazing. I like this answer more, but it leaves another question: What did Hevel do when there was no more grass for his sheep to eat?</div><div>
