“Then Joseph got up.
He took the child
With his mother,
They withdrew to Egypt.
He remained there,
Until the death of Herod.”
ὁ δὲ ἐγερθεὶς παρέλαβεν τὸ παιδίον καὶ τὴν μητέρα αὐτοῦ νυκτὸς καὶ ἀνεχώρησεν εἰς Αἴγυπτον,
καὶ ἦν ἐκεῖ ἕως τῆς τελευτῆς Ἡρῴδου·
Joseph woke up (ὁ δὲ ἐγερθεὶς) from his sleep after the dream of the angel of the Lord. Then at night (νυκτὸς), he took the child with his mother (παρέλαβεν τὸ παιδίον καὶ τὴν μητέρα αὐτοῦ). They went or withdrew into Egypt (ἀνεχώρησεν εἰς Αἴγυπτον), just as he had been told to do. Joseph clearly followed the instructions that he got in his dream. He took his whole family, without hesitation, under the cover of darkness at night, into an unknown place in Egypt. They stayed someplace in Egypt (ἦν ἐκεῖ ἕως), until Herod would die (τῆς τελευτῆς Ἡρῴδου). There is no indication of where they went in Egypt.
