'Assumed' in the Bible

Of the sons of the priests: the sons of Hobaiah, of Hakkoz, and of Barzillai, who took a wife from the daughters of Barzillai the Gileadite, and he was known by their name.

But the former governors who were [in office] before me put heavy burdens on the people and took food and wine from them in addition to forty shekels of silver [as an excessive monthly salary]; even their servants assumed authority over the people. But I did not do so because of the [reverent] fear of God.
