'Charge' in the Bible

and they burn unto Jehovah every morning and every evening burnt-offerings and sweet incense: the showbread also'set they in order upon the pure table; and the candlestick of gold with the lamps thereof, to burn every evening: for we keep the charge of Jehovah our God; but ye have forsaken him.

But let none come into the house of Jehovah, save the priests, and they that minister of the Levites; they shall come in, for they are holy: but all the people shall keep the charge of Jehovah.

For there were many in the assembly that had not sanctified themselves: therefore the Levites had the charge of killing the passovers for every one that was not clean, to sanctify them unto Jehovah.
