'Manner' in the Bible

Then a trustworthy king will be established; he will rule in a reliable manner, this one from David's family. He will be sure to make just decisions and will be experienced in executing justice.

Listen to this, O family of Jacob, you who are called by the name 'Israel,' and are descended from Judah, who take oaths in the name of the Lord, and invoke the God of Israel -- but not in an honest and just manner.
