'Enjoined' in the Bible

To confirm these days of Purim in their times appointed, according as Mordecai the Jew and Esther the queen had enjoined them, and as they had decreed for themselves and for their seed, the matters of the fastings and their cry.

Who hath enjoined him his way? or who can say, Thou hast wrought iniquity?

Saying, This is the blood of the testament which God hath enjoined unto you.
