Exodus 21:19

then if the man rises again and walks outdoors with his staff , he who struck him shall be clear ; only he shall pay for the loss of his time , and shall have him thoroughly healed .

the one who struck the blow will not be held liable if the other can get up and walk around outside with a staff; however, the guilty party must pay the injured person for any loss of time and see that the victim is completely healed.

If he rise again, and walk abroad upon his staff, then shall he that smote him be quit : only he shall pay for the loss of his time, and shall cause him to be thoroughly healed.
