'Right' in the Bible

And he was pleased with the girl and was kind to her; and he quickly gave her what was needed for making her clean, and the things which were hers by right, and seven servant-girls who were to be hers from the king's house: and he had her and her servant-girls moved to the best place in the women's part of the house.

And Haman said to King Ahasuerus, There is a certain nation living here and there in small groups among the people in all the divisions of your kingdom; their laws are different from those of any other nation, and they do not keep the king's laws: for this reason it is not right for the king to let them be.

And the king said to Haman, The money is yours, and the people, to do with them whatever seems right to you.

And King Ahasuerus said to Queen Esther, "Who [is] he, and where [is] he, who {gave himself the right to do this}?"

And said, If it please the king, and if I have found favour in his sight, and the thing seem right before the king, and I be pleasing in his eyes, let it be written to reverse the letters devised by Haman the son of Hammedatha the Agagite, which he wrote to destroy the Jews which are in all the king's provinces:

The king’s edict gave the Jews in each and every city the right to assemble and defend themselves, to destroy, kill, and annihilate every ethnic and provincial army hostile to them, including women and children, and to take their possessions as spoils of war.
