As for the earth, out of it cometh bread: and under it is turned up as it were fire.
Its fertile surface yields food; and yet 'beneath it is turned up as it were by fire.' So Pliny ('Natural History,' 33:) observes on the ingratitude of man, who repays the debt he owes the earth for food by digging out its bowels. 'Fire' was used in mining (Umbreit). The English version is simpler, which means precious stones which glow like fire; and so Job 28:6 follows naturally (Ezekiel 28:14, "stones of fire").
