Narrative:
During engine start and disconnecting of external power; first officer obtained pushback clearance. I heard and understood: 'cleared to push '2-8-left.' I instructed the ramp 'brakes released; cleared to push; tail west.' just prior to the airplane crossing the service road; I sighted a B737 approaching from the left and simultaneously heard ATC instruct us to hold the push. I commanded a stop and the tug driver complied admirably. I commanded a pull of the airplane back toward the parking spot to ensure that the taxiway behind my aircraft was clear for B737 to pass. After B737 passed; ATC reclred us to pushback. The remainder of the flight went off as planned and without incident. Post event discussion with the first officer indicated that he did; in fact; hear an instruction to wait for B737 to pass before the cleared to push statement.
