'Kept' in the Bible

"Command Aaron and his sons, saying, 'This [is] the regulation of the burnt offering: {The burnt offering must remain on the hearth} on the altar all night until the morning, and the altar's fire must be kept burning on it.

but the fire on the altar must be kept burning on it; it must not be quenched. And the priest must burn wood {every morning} on it, and he shall arrange the burnt offering on it, and he shall turn into smoke the fat portions of the fellowship offerings on it.

A perpetual fire must be kept burning on the altar; it must not be quenched.
