'Conceal' in the Bible

Judah said to his brothers, "What profit is it if we kill our brother and conceal his blood?

you shall not consent to him, nor listen to him; neither shall your eye pity him, neither shall you spare, neither shall you conceal him:

I will teach you about the hand of God. That which is with the Almighty will I not conceal.

It is the glory of God to conceal a thing, but the glory of kings is to search out a matter.

Declare among the nations and publish, and set up a standard; publish, and don't conceal: say, Babylon is taken, Bel is disappointed, Merodach is dismayed; her images are disappointed, her idols are dismayed.
