Bd7 develops the bishop to its only good square at the moment. This move also has a second purpose: to free the c8 square for the rook. In the Open Sicilians, Black gets a half open c-file in exchange for White's half-open d-file, and Bd7/Rc8 is a good way to take advantage of it. Rc8 also threatens White's c4-bishop, forcing it to move out of danger with most commonly Bb3.
