it's not where you are, it's where you are headed that's important

At the very end of last week's parsha, when Yaakov was on the road out of Charan, he came to a "machaneh Elokim," an encampment of angels, and he named the place Machanayim (32:2-3).  Rashi writes that he named the place Machanayim, in the plural, because there were two groups of angels there: the angels of chutz la'aretz who had accompanied him until that point, and the angels of Eretz Yisrael who had come to escort him home.  Ramban disagrees.  How could Yaakov have met the angels of Eretz Yisrael in Machanayim when we first read in this upcoming week's parsha that he crossed Maavar Yabok, which was the border of Amon's territory, not Eretz Yisrael.  Yaakov still had to pass through the lands of Amon, Moav, and then Edom and only then would he reach Eretz Yisrael, after the encounter with Eisav that we will read about this week.   

Maharal in Gur Aryeh answers that what's important is not where you are, what's important is where you are headed.  

ולפי דעתי אין זה שום קושיא, דכיון דהיה הולך ובא לארץ ישראל - באו המלאכים של ארץ ישראל לקראתו לשמור אותו, דכיון דצורך ארץ ישראל הוא, והוא הולך לארץ ישראל, הדין נותן שיהיו לו שומרים מלאכי ארץ ישראל, לכל הפחות השמירה דבר שהוא תולה בהליכה, שלא יהיה לו מונע לבא לארץ ישראל

The malachim of Eretz Yisrael don't come to greet you only when you touch down at Ben Gurion.  The malachim of Eretz Yisrael already come to help out when you check in at JFK, or wherever you are flying from (G-d knows you can use help to navigate the hoops they make you jump through at check-in time these days).

(See Maharal as to why the angels came now and not as soon as Yaakov left Lavan's house, and other details that he irons out).
