What does Luke 1:58 mean?

Both Elizabeth (Luke 1:57) and Zechariah are known for their godly lives (Luke 1:5–7). They have struggled with an inability to have children, however. While Zechariah was serving in the temple, he was visited by an angel, Gabriel (Luke 1:11–12). Gabriel declared that Elizabeth would finally have a son, who would be an important prophet (Luke 1:13–17). Zechariah's first response was doubt, so he was temporarily stricken with an inability to speak (Luke 1:19–20).

As expected, Elizabeth was overjoyed with this news (Luke 1:24–25). Also as expected, her friends and family were happy for her, as well. Given the circumstances of his birth and his father's encounter with Gabriel, there would have been more interest than usual. This means that the baby's circumcision and naming were likely attended with great interest. This would have multiplied the number of people who saw the supernatural events which occurred there (Luke 1:63–66).
