New Defender's Study Bible Notes
53:10 prolong his days. Once “His soul” was offered for sin, then the whole theme changes from suffering to triumph just as in Psalm 22:30. His days are “prolonged” (even though He had died) and He soon sees the resulting spiritual “seed” (John 12:24; Hebrews 2:10).
53:11 travail of his soul. Note that it was “the travail of His soul,” rather than of His suffering body, which produced the seed.
53:11 my righteous servant. This could better read: “By the knowledge of Him shall my righteousness as the servant” justify many.
53:11 bear their iniquities. Note II Corinthians 5:21. Because He bore our iniquities, we receive His righteousness.
