The Scriptures are clearly speaking of a person, not a nation. That person is Jesus the Messiah (Christ).
Isaiah 7
[3] He is despised and rejected of men; a man of sorrows, and acquainted with grief: and we [the Jewish people] hid as it were our faces from him; he was despised, and we esteemed him not.
[4] Surely he hath borne our griefs, and carried our sorrows: yet we did esteem him stricken, smitten of God, and afflicted.
[5] But he was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed.
[6] All we like sheep have gone astray; we have turned every one to his own way; and the Lord hath laid on him the iniquity of us all.
