Narrative:
We were at the end of runway 33 at dca waiting for takeoff. Tower instructed us to line up and wait. As I was proceeding to line up and wait; tower issued a different clearance to turn to 280 degrees and maintain 3000 ft. After departure. The co-pilot read back the new issued clearance and for some reason thought we were cleared for takeoff. I lined up and stopped. The co-pilot asked if I was ready to go. I asked the co-pilot if we were cleared for takeoff. He responded; yes. Concentrating on positioning the aircraft to line up on the runway as we were issued a new clearance and the heavy traffic on the radio at that time; I thought I might have not heard the tower clear us for takeoff. I proceeded takeoff roll down the runway when tower told us to abort. I believe where the miscommunication started was when the tower issued us a new clearance while we were taxiing onto the runway; to turn to a new heading of 280 degrees and maintain 3000 ft. But did not tell us to continue to hold. After receiving the new clearance; we assumed we were cleared for takeoff. A very serious lesson to be learned here. If you are ever in doubt or unsure of any communication between you and ATC; always verify. I have verified many times with controllers in my flying career; but this time I did not. And because of that; a terrible outcome could have happened because of it.
