It seems that names are taken with special care in the Bible:
THE THIRD COMMANDMENT:You shall not take the name of the Lord your God in vain, for the Lord will not hold him guiltless who takes His name in vain" (Exodus 20:7)
- Jacob's name is changed to Israel (Genesis 32:22-32).
- Saul's name is changed to Paul (Acts 13:9).

MY QUESTION IS: Why are names taken so carefully in the Bible? Is it tradition or God's will?
