9 Be careful, however, that the exercise of your rights does not become a stumbling block to the weak.

But take heed lest by any means this liberty of yours become a stumblingblock to them that are weak.
But take care that this right of yours does not somehow become a stumbling block to the weak.
But you must be careful so that your freedom does not cause others with a weaker conscience to stumble.
