Jamieson Faussset Brown Commentary

Verse 21. And he arose, and took the young child and his mother, and came into the land of Israel–intending, as is plain from what follows, to return to Bethlehem of Judea, there, no doubt, to rear the Infant King, as at His own royal city, until the time should come when they would expect Him to occupy Jerusalem, “the city of the Great King.”

People’s New Testament Commentary

And arose and took the young child. He obeyed as promptly as before, waiting obediently upon the Divine will.  

Came into the land of Israel. This included not only Judea, but Samaria, Galilee and the country beyond the Jordan. The part first reached by Joseph on his return would be Judea.
