[53:10] 1 tn The meaning of this line is uncertain. It reads literally, “if you/she makes, a reparation offering, his life.” The verb תָּשִׂים (tasim) could be second masculine singular,in which case it would have to be addressed to the servant or to God. However, the servant is only addressed once in this servant song (see 52:14a), and God either speaks or is spoken about in this servant song; he is never addressed. Furthermore, the idea of God himself making a reparation offering is odd. If the verb is taken as third feminine singular, then the feminine noun נֶפֶשׁ (nefesh) at the end of the line is the likely subject. In this case one can take the suffixed form of the noun as equivalent to a pronoun and translate, “if he [literally, “his life”] makes a reparation offering.”
[53:10] 2 sn The idiomatic and stereotypical language emphasizes the servant’s restoration to divine favor. Having numerous descendants and living a long life are standard signs of divine blessing. See Job 42:13-16.
