Narrative:
Ground control gave us a clearance to taxi via B; B2 and cross runway xy at B2. We headed south on B; turned right (west) onto B2 to cross runway xy. As we were on B2 crossing runway xy; I heard ground controller state 'aircraft on B4 stop; hold position; aircraft on B4 stop immediately.' we were on B2 but I had been listening to other calls on ground and no one should have been on B4; so I thought he might be talking to us (this took less than one second) and as I continued to scan ahead I saw a helicopter north bound on runway xy low level. (I believe the helicopter had come from his base eastbound; overflew taxiway a and then turned low level northbound on runway xy).the pilot flying and I both hit the brakes immediately as the helicopter passed in front of us. Probable cause of near collision; ground controller gave a us taxi clearance with runway crossing instructions; the tower controller gave the helicopter a clearance to depart north bound on runway xy and failed to realize we were taxiing.
