ISB ~ Matthew 8 v17

He took our infirmities:A formula quotation from Is 53:4. Jesus fulfills this role by physical healings. Peter evokes the same OT context to speak also of Jesus’ spiritual healing of sinners (1 Pet 2:24-25; cf. Is 53:5-6).

• Isaiah foretold of a Servant figure who would take Israel’s sins upon himself and heal God’s people (Is 52:13-53:12). This Servant would inaugurate the restoration of the tribes of Israel and bring the Gentiles to the family of God (Is 49:6). Matthew sees Jesus in this role, ushering in the kingdom by expelling demons and healing diseases. The close relationship between sin and physical affliction is assumed (cf. Ps 107:17; Is 33:24; CCC 1505).
