kjv@Genesis:35:10@ And God said unto him, Thy name is Jacob: thy name shall not be called any more Jacob, but Israel shall be thy name: and he called his name Israel.
His name is being changed from Jacob (supplanter) to Israel (he will rule as God). It not only marks a change in the present perception but, in the goal or direction spiritually for him to follow. Name changes were more common in that day and notated the turning over of a new leaf.
