Genesis 32:15

Thirty milch camels with their colts
Milch camels were in great esteem in the eastern countries; their milk being, as Aristotle ^F25 and Pliny ^F26 say, the sweetest of all milk: forty kine and ten bulls;
one bull to ten cows; the same proportion as in the goats and rams: twenty she asses and ten foals;
and supposing thirty colts belonging to the camels; the present consisted of five hundred and eighty head of cattle: a large number to spare out of his flocks and herds, that he had acquired in six years' time; and showed a generous disposition as well as prudence, to part with so much in order to secure the rest.
