'Command' in the Bible

Of the sons of Issachar, men who understood the times, with knowledge of what Israel should do, their chiefs were two hundred; and all their kinsmen were at their command.

But he did not number Levi and Benjamin among them, for the king’s command was abhorrent to Joab.

Now behold, there are the divisions of the priests and the Levites for all the service of the house of God, and every willing man of any skill will be with you in all the work for all kinds of service. The officials also and all the people will be entirely at your command.”
