What does the Torah mean when it continues "ve'Lo Sikchu Kofer Lanus el lr Miklato"?
Rashi: 'Do not accept ransom money for the life of a Rotze'ach be'Shogeg who has fled to his Ir Miklat - in order to allow him to return home before the Kohen Gadol dies. 1
Moshav Zekenim citing his Rebbi: Also this verse discusses a Mezid murderer. Verse 31 forbids accepting ransom to totally exempt a Mezid murderer, and our verse forbids accepting ransom to allow him to flee to and stay in an Ir Miklat. 2
Rashi: "la'Nus" is synonymous with "le'Nas" ('to the one who fled') - like "Shuvei Milchamam" (in Michah, 2:8) which means 'who returned from the battle-field' and "ki Mulim Hayu" (in Yehoshua, 5:5, which means 'who were circumcised'). Refer to 35:32:151:1 and the note there.
Moshav Zekenim: This is difficult, for Makos 9b says that our verse discusses a Shogeg murderer!
And what does the Torah mean when it continues "ve'Lo Sikchu Kofer la'Nus el lr Miklato"?
Rashi, Ramban, Targum Onkelos and Targum Yonasan: 'Do not accept ransom money for the life of a Rotze'ach be'Shogeg who has fled 1 to his Ir Miklat
Rashi: "La'nus" is equivalent to "le'Nas"
Rashi writes that "Lanus" is like "la'Nas." We never find a verb expounded like this in the Torah! Why can it not mean literally 'do not accept ransom from a Rotze'ach who is obligated to go to an Ir Miklat?
