Miscom on heading clearance prior to takeoff. Flight crew thought 140 degrees and clearance was 240 degrees. That heading took them into a glider flying area and they came close to a glider before ATC corrected their heading.

Narrative:
First officer and I both believed 140 degrees was the heading assigned to 'keep south of gliders.' first officer read 140 degrees back. Later controller advised us we were in glider area and should have been on a 240 degree heading. Miscom with controller.
