Apocalipse 6:6

6 Then I heard what sounded like a voice among the four living creatures, saying, "Two pounds Or about 1 kilogram of wheat for a day's wages, Greek [a denarius] and six pounds Or about 3 kilograms of barley for a day's wages, Greek [a denarius] and do not damage the oil and the wine!"

6 And a voice came to my ears, from the middle of the four beasts, saying, A measure of grain for a penny, and three measures of barley for a penny: and see that you do no damage to the oil and the wine.
