Jeremiah 31:21-22

Jeremiah 31:21-22. Set thine heart toward the highway, even the way which thou wentest: turn again, O virgin of Israel, turn again to these thy cities. How long wilt thou go about, O thou backsliding daughter? for the LORD hath created a new thing in the earth, A woman shall compass a man.

Whereas the enemy had compassed Jerusalem round about, now Jerusalem was to be the besieger, and to compass her enemies, and defeat them. Some interpreters think this is an allusion to the birth of the Saviour, that "new thing in the earth" - the incarnation of the Son of God.
