Jesus' Substitutionary Descent into Egypt

Do you ever find yourself scratching your head about how Matthew uses the Old Testament? It seems to be a common experience. It really should not be as difficult for us to understand as it is. Yet our received methods make it hard for us to handle Scripture biblically.

But here I do not want to take time to discuss how our modernist methods have moved us away from an apostolic and Christ-like handling of Scripture (for that, see Peter Leithart's book Deep Exegesis). I only want to provide a compact understanding of Matthew's usage of Hos. 11:1 in Matt. 2:15 given by William Dumbrell, since it is considered one of the more difficult texts in Matthew's use of the Old Testament:

Matthew's use of Hosea 11:1 (Matt. 2:15) has the sequence [from 11:1-11] in mind. Jesus in an incarnational descent into Egypt undergoes oppression with his people, to whom, although they do not deserve it, the possibility of a second exodus will be granted (The Faith of Israel, 182).

This seems plain. And if one mentally embraces the deep and wide theological structures of Scripture that include Jesus as the new and true Israel and as a second Adam, the representative head of a new humanity and holy nation, the reading is almost facile.
