To deserted places
αὐτὸς δὲ ἦν ὑποχωρῶν ἐν ταῖς ἐρήμοις καὶ προσευχόμενος.
This is a unique saying about Jesus that is not found elsewhere. Luke said that Jesus would withdraw (αὐτὸς δὲ ἦν ὑποχωρῶν) to deserted places (ἐν ταῖς ἐρήμοις) to pray (καὶ προσευχόμενος). Notice the emphasis on the role of solitary prayer in Luke.
