'Attendant' in the Bible

So Moses arose with Joshua his attendant, and he went up to the mountain of God.

Every day Mordecai [who was an attendant in the king’s court] walked back and forth in front of the courtyard of the harem to learn how Esther was getting along and what was happening to her.

Now as for Esther, the daughter of Abihail the uncle of Mordecai who had taken her in as his [own] daughter, when her turn came to go in to the king, she requested nothing except what Hegai the king’s eunuch [and attendant] who was in charge of the women, advised. And Esther found favor in the sight of all who saw her.

The commander of the officials gave them [Babylonian] names: Daniel he named Belteshazzar, Hananiah he named Shadrach, Mishael he named Meshach, and Azariah he named Abed-nego.
