11. Jehovah is still speaking.
      see of the travail--He shall see such blessed fruits resulting from His sufferings as amply to repay Him for them (Isa 49:4, 5; 50:5, 9). The "satisfaction," in seeing the full fruit of His travail of soul in the conversion of Israel and the world, is to be realized in the last days (Isa 2:2-4).
      his knowledge--rather, the knowledge (experimentally) of Him (Joh 17:3; Php 3:10).
      my . . . servant--Messiah (Isa 42:1; 52:13).
      righteous--the ground on which He justifies others, His own righteousness (1Jo 2:1).
      justify--treat as if righteous; forensically; on the ground of His meritorious suffering, not their righteousness.
      bear . . . iniquities-- (Isa 53:4, 5), as the sinner's substitute.
