KJV: The Jews ordained, and took upon them, and upon their seed, and upon all such as joined themselves unto them, so as it should not fail, that they would keep these two days according to their writing, and according to their appointed time every year;
NASB: the Jews established and made a custom for themselves and for their descendants and for all those who allied themselves with them, so that they would not fail to celebrate these two days according to their regulation and according to their appointed time annually.
KJV: And that these days should be remembered and kept throughout every generation, every family, every province, and every city; and that these days of Purim should not fail from among the Jews, nor the memorial of them perish from their seed.
NASB: So these days were to be remembered and celebrated throughout every generation, every family, every province and every city; and these days of Purim were not to fail from among the Jews, or their memory fade from their descendants.
KJV: To confirm these days of Purim in their times appointed, according as Mordecai the Jew and Esther the queen had enjoined them, and as they had decreed for themselves and for their seed, the matters of the fastings and their cry.
NASB: to establish these days of Purim at their appointed times, just as Mordecai the Jew and Queen Esther had established for them, and just as they had established for themselves and for their descendants with instructions for their times of fasting and their lamentations.
KJV: For Mordecai the Jew was next unto king Ahasuerus, and great among the Jews, and accepted of the multitude of his brethren, seeking the wealth of his people, and speaking peace to all his seed.
NASB: For Mordecai the Jew was second only to King Ahasuerus, and great among the Jews and in favor with his many kinsmen, one who sought the good of his people and one who spoke for the welfare of his whole nation.
