GEN998 The Bible never uses the word chosen in relation to the Jews as an adjective, but rather as a verb [note: literally, y’da’tiv – “I have known him” – AJL], thereby conveying the idea that they were chosen for a purpose.   God has no favorite nations.   Consider, “No, for I have chosen him, that he may charge his children and his household after him to keep the way of the Lord by doing righteousness and justice;… Or again, “Happy is the nation whose God is the Lord, the people whom he has chosen as his heritage” Psalm 33:12. The verse makes it clear that the Jews are chosen as God’s witnesses to other nations to make Him known.  BOTEACH 277-8
