When eight days had passed and it was time to circumcise him, he was named Jesus — the name the angel had given him before he was conceived in the womb.
In context
19But Mary treasured all these words and turned them over in her heart. 20The shepherds went back, giving glory and praise to God for everything they had heard and seen, just as it had been told to them. 21When eight days had passed and it was time to circumcise him, he was named Jesus — the name the angel had given him before he was conceived in the womb. 22When the days of their purification were complete, according to the law of Moses, they brought him up to Jerusalem to present him to the Lord, 23as it is written in the law of the Lord: every male who is first to open the womb shall be called holy to the Lord.
