to hide: to take cover out of sight, to conceal or shelter another person or thing, or to be kept from view, usually to escape danger or stay safe
The verb chava is the plain Hebrew word for getting out of sight. Most often it describes a person taking cover: fleeing to a cave, crouching in a field, or slipping away when an enemy or danger is near. Adam and Eve hiding among the trees, David hiding from Saul, and whole armies hiding in the hills are all this one word.
The same verb works the other way around too, for putting someone else out of sight to keep them safe: Rahab hiding the spies on her roof, Obadiah hiding a hundred prophets in caves, a nurse keeping the infant prince Joash hidden in the temple. It can also describe simply being hidden or kept from view, whether a prisoner shut away or, in a poem, floodwaters locked under ice.
In every case the word stays concrete and physical. It is about people and things out of sight, usually with fear or safety in view, not about concealing feelings or secrets. That plainness is why the single English word "hide" fits it so well.
