if he recovers and can walk outside with a staff, the one who struck him goes unpunished, except that he must pay for the loss of his time and see that he is completely healed.
In context
17Whoever curses his father or mother shall surely be put to death. 18If men quarrel and one strikes the other with a stone or with his fist, and the man does not die but is confined to bed — 19if he recovers and can walk outside with a staff, the one who struck him goes unpunished, except that he must pay for the loss of his time and see that he is completely healed. 20If a man strikes his male or female servant with a rod, and the servant dies under his hand, he shall be punished. 21But if the servant survives a day or two, he is not to be punished, since the servant is his property.
