This week we continue the Ya’akov saga in our Torah, and we encounter the passage where Ya’akov wrestles all night with a mysterious stranger – finally at daybreak Yaakov receives another name – Israel. When is he called Israel and when Ya’akov? Why does he need a new name? What does it mean when we change our name or add to our names – as we do when we receive our Jewish names, wither by our parents or by our choice? When do we use those names?
