'Charges' in the Bible

And the priests stood in their charges, and the Levites with Jehovah's instruments of music, which David the king had made to praise Jehovah, for his loving-kindness endureth for ever, when David praised by their means; and the priests sounded the trumpets opposite to them, and all Israel stood.

And he appointed, according to the ordinance of David his father, the divisions of the priests for their service, and the Levites for their charges, to praise and serve before the priests, as the duty of every day required; and the doorkeepers by their divisions at every gate: for such was the commandment of David the man of God;

besides those from three years old and upward who as males were entered in the genealogical register, all that came into the house of Jehovah, as the duty of every day required, for their service in their charges, according to their divisions,

both to the priests enregistered according to their fathers' houses, and to the Levites from twenty years old and upward, in their charges, by their divisions;

And he set the priests in their charges, and encouraged them to the service of the house of Jehovah.
