אָ֗ח לֹא־פָדֹ֣ה יִפְדֶּ֣ה אִ֑ישׁ לֹא־יִתֵּ֖ן לֵאלֹהִ֣ים כָּפְרֽוֹ׃
pas un ne saurait racheter son frère, ni donner à Dieu le coût de sa rançon.
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.
