Why was the Holy Family instructed to flee to Egypt?

At Matthew 2:13-14 (NRSVCE)we read about the flight of the Holy Family to Egypt: " Now after they had left, an angel of the Lord appeared to Joseph in a dream and said, “Get up, take the child and his mother, and flee to Egypt, and remain there until I tell you; for Herod is about to search for the child, to destroy him.” Then Joseph got up, took the child and his mother by night, and went to Egypt" My question is: what were the advantages that Egypt offered as a shelter for the Jewish family in the post-exodus scenario in which the then generation of Egyptians would have only hatred for the Israelites in their genes ? What are the views of the Catholic Church on the divine selection of Egypt as the shelter for the Holy Family ?
