'Charge' in the Bible

And David rose up early in the morning, and left the sheep with a keeper, and took his charge and went, as Jesse had commanded him. And he came to the wagon-defence; and the host which was going forth to the battle-array shouted for the fight.

Was it to-day that I began to inquire of God for him? be it far from me: let not the king charge anything to his servant, nor to all the house of my father; for thy servant knew nothing of all this, less or more.
