Jerome of Stridon
In the Hebrew context, the term olam (עולם), which translates to century, embodies the concept of eternity when the letter vav is included. Conversely, when the letter vav is absent, it refers to the fiftieth year, known as the jubilee year. This is why a Jewish individual, who out of affection for his family and loyalty to his master, chooses to enter servitude through the piercing of his ear, is instructed to serve for a lifetime—interpreted as lasting until the jubilee year. (Galatians 1:4-5)
