אָ֗ח לֹא־פָדֹ֣ה יִפְדֶּ֣ה אִ֑ישׁ לֹא־יִתֵּ֖ן לֵאלֹהִ֣ים כָּפְרֽוֹ׃
Ни один человек не может ни выкупить своего брата, ни дать Богу выкуп за него—
Rashi on Psalms
A brother cannot ransom his brother with money because the ransom of their soul is dearer than any possession. Therefore, perforce, his redemption is forever unattainable.
