Many people that come out of pagan practices and into a Torah observant life through teshuva (repentance), choose to take on a Hebrew name for themselves based on Proverbs 22:1. Isolated, it appears that this is a correct interpretation of the passage, and there was a time when I interpretted the same way. There are several limited examples in the body of scripture where Elohim gave someone a new name: Abram:Abraham, Sarai:Sarah, Jacob:Israel, etc... And there are others within the Midrashim.
Proverbs (Mishle) 22:
1 A good name is rather to be chosen than great riches, and loving favour rather than silver and gold.
