'Charge' in the Bible

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

For there were many in the congregation that were not hallowed; therefore the Levites had the charge of the slaughtering of the passover-lambs for every one not clean, to hallow them unto Jehovah.
