Makkos 3:4-5
Makkos 3:4
Rabbi Yehuda says that if a person took both a mother bird and her young, he is lashed but he no longer needs to send the mother away. The Sages say that he must send the mother bird away but he is not lashed. The general principle is that if a prohibition can be rectified by a subsequent obligation, one is not lashed for it.
Makkos 3:5
If a man made a bald spot on his head, cut off his payes, shaved his beard, or made a single cut for the dead, he is liable. If he made one cut for five who were dead, or five cuts for one who was dead, he is liable for each of them. For cutting off his payes, one is liable twice – once for each side of his head. For shaving off his beard, a person is liable for five spots – two on each side of his head and one for his chin. Rabbi Eliezer says that if he removed his entire beard at once, he is only liable once. One is not liable unless he removes his beard using a razor; Rabbi Eliezer says that one is liable even if he plucked out his beard using tweezers or cut it off with an axe.
