GENESI 25:26

Appresso uscì il suo fratello, il quale con la mano teneva il calcagno di Esaù; e gli fu posto nome Giacobbe . Or Isacco era d'età di settant'anni, quando ella li partorì.

And after that came his brother out, and his hand took hold on Esau’s heel; and his name was called Jacob: and Isaac was threescore years old when she bare them.
