Isa 53:10
Yet it pleased Hashem to bruise him; He hath put him to suffering; when Thou shalt make his nefesh an asham offering for sin,
LXX-
Isa 53:10 And the LORD willed to cleanse him of the beating. If you should offer for a sin offering the thing for your life, he shall see [seed a long-lived].
I don't follow the LXX as my authoritative source.
he (Moshiach) shall see zera [see Psalm 16 and Yn 1:12 OJBC], He shall prolong his yamim (days) and the chefetz Hashem (pleasure, will of Hashem) shall prosper in his [Moshiach's] hand.
Isa 53:11 He [Hashem] shall see of the travail of his [Moshiach's] nefesh, and shall be satisfied; by knowledge of him [Moshiach] shall Tzadik Avdi ["My Righteous Servant," Moshiach, Zecharyah 3:8, Yirmeyah 23:5; Zecharyah 6:11-12, Ezra 3:8 Yehoshua, Yeshua shmo] justify many (Ro 5:1); for he [Moshiach] shall bear their avon (iniquities).
Isa 53:12 Therefore will I divide him a portion with the great, and he shall divide the spoil with the strong; because he hath poured out his nefesh unto mavet (death); and he was numbered with the transgressors; and he nasah (Lv 16:22, carried) (like the Yom Kippur scapegoat) the sin of many, and made intercession [did the work of a mafgi'a, intercessor] for the transgressors [see Lk 23:34 OJBC].
