Lamp Under a Basket
Light is meant to be seen; hiddenness is temporary.
Jesus uses the lamp to speak about revelation and responsibility: what is received is meant to illuminate, and hidden things will be disclosed.
Scripture
21 He said to them, "Is the lamp brought to be put under a basket or under a bed? Isn't it put on a stand?
22 For there is nothing hidden, except that it should be made known; neither was anything made secret, but that it should come to light.
23 If any man has ears to hear, let him hear."
24 He said to them, "Take heed what you hear. With whatever measure you measure, it will be measured to you, and more will be given to you who hear.
25 For whoever has, to him will more be given, and he who doesn't have, even that which he has will be taken away from him."
16 "No one, when he has lit a lamp, covers it with a container, or puts it under a bed; but puts it on a stand, that those who enter in may see the light.
17 For nothing is hidden, that will not be revealed; nor anything secret, that will not be known and come to light.
18 Be careful therefore how you hear. For whoever has, to him will be given; and whoever doesn't have, from him will be taken away even that which he thinks he has."
33 "No one, when he has lit a lamp, puts it in a cellar or under a basket, but on a stand, that those who come in may see the light.
34 The lamp of the body is the eye. Therefore when your eye is good, your whole body is also full of light; but when it is evil, your body also is full of darkness.
35 Therefore see whether the light that is in you isn't darkness.
36 If therefore your whole body is full of light, having no part dark, it will be wholly full of light, as when the lamp with its bright shining gives you light."
