“And it came to pass, that on the eighth day they came to circumcise the child; and they called him Zacharias, after the name of his father.”
King James Version (KJV)
Lu 1:59 On the eighth day. On the eighth day male Jewish children were circumcised and named (Ge 17:12). The kinsmen present called the child after his father's name, a common Jewish custom, but Elizabeth protested that his name should be John, that given by the angel. The matter was referred to the father.
