“Then Herod secretly called
For the Magi.
The exact time
When the star had appeared.”
Τότε Ἡρῴδης λάθρᾳ καλέσας τοὺς μάγους ἠκρίβωσεν παρ’ αὐτῶν τὸν χρόνον τοῦ φαινομένου ἀστέρος
Then Herod (Ἡρῴδης) secretly called (λάθρᾳ καλέσας) the magi (τοὺς μάγους). It is not clear why he had to do this secretly, since they seem to have publicly went to him. He wanted to know from them (ἠκρίβωσεν παρ’ αὐτῶν) the exact time (τὸν χρόνον) when this star had first appeared (τοῦ φαινομένου ἀστέρος). This was an attempt by Herod to figure out when this new king was born.
