Mark 4:21
He said to them, do you bring in a lamp to put it under a bowl or a bed? Instead, don't you put it on its stand? — the lamp proverb introduces the second section of the Markan parable discourse, addressing the purpose and inevitability of the kingdom's disclosure. A lamp is made to give light; the only way to prevent a lamp from fulfilling its purpose is to cover it. The bowl (modion, a measuring basket) and the bed are both covers — the lamp under the bowl is a waste of lamp; the lamp under the bed is a fire hazard. The implied application: the kingdom's light has not been hidden in order to stay hidden but in order to be revealed.
