'Charge' in the Bible

and give them a charge unto their masters, saying, Thus saith Jehovah of hosts, the God of Israel, Thus shall ye say unto your masters:

Now Nebuchadrezzar king of Babylon gave charge concerning Jeremiah to Nebuzaradan the captain of the guard, saying,

How canst thou be quiet, seeing Jehovah hath given thee a charge? Against Ashkelon, and against the sea-shore, there hath he appointed it.
