'Kept' in the Bible

“Command Aaron and his sons: This is the law of the burnt offering; the burnt offering itself must remain on the altar’s hearth all night until morning, while the fire of the altar is kept burning on it.

The fire on the altar is to be kept burning; it must not go out. Every morning the priest will burn wood on the fire. He is to arrange the burnt offering on the fire and burn the fat portions from the fellowship offerings on it.

Fire must be kept burning on the altar continually; it must not go out.
