'Conceals' in the Bible

a man has sexual relations with her and she conceals it from her husband, keeping it secret although she has defiled herself with there being no witnesses against her, but she was caught anyway.

Though evil tastes sweet in his mouth, though he conceals it under his tongue,

"If he remains silent, who will condemn him? If he conceals his face, who can see him? He watches over both nation and individual alike,

What the righteous say is a flowing fountain, but what the wicked say conceals violence.

Whoever conceals hatred is a deceitful liar, and whoever spreads slander is a fool.

"Indeed, the LORD God of Israel says that he hates divorce, along with the one who conceals his violence by outward appearances," says the LORD of the Heavenly Armies. "So guard yourselves carefully, and don't be unfaithful."
