'Seed' in the Bible

And Haman gave his wife Zeresh and all his friends an account of what had taken place. Then his wise men and his wife Zeresh said to him, If Mordecai, who is starting to get the better of you, is of the seed of the Jews, you will not be able to do anything against him, but you will certainly go down before him.

The Jews made a rule and gave an undertaking, causing their seed and all those who were joined to them to do the same, so that it might be in force for ever, that they would keep those two days, as ordered in the letter, at the fixed time every year;

And that those days were to be kept in memory through every generation and every family, in every division of the kingdom and every town, that there might never be a time when these days of Purim would not be kept among the Jews, or when the memory of them would go from the minds of their seed.

Giving the force of law to these days of Purim at their fixed times, as they had been ordered by Mordecai the Jew and Esther the queen, and in keeping with the rules they had made for themselves and their seed, in connection with their time of going without food and their cry for help.

For Mordecai the Jew was second only to King Ahasuerus, and great among the Jews and respected by the body of his countrymen; working for the good of his people, and saying words of peace to all his seed.
