'Powerful' in the Bible

For Mordecai exercised great power in the palace, and his fame spread throughout the provinces as he became more and more powerful.

All of his powerful and magnificent accomplishments and the detailed account of Mordecai’s great rank to which the king had honored him, have they not been written in the Historical Records of the Kings of Media and Persia?

Indeed, Mordecai the Jew was second in authority only to King Ahasuerus and was a powerful official among the Jewish people. Mordecai was accepted favorably by his many kinsmen, and he sought the good of his countrymen and spoke out for the welfare of all his people.
