'Hand' in the Bible

It will be like a man who runs from a lion, only to encounter a bear; or who comes home, leans his hand against a wall, and a serpent bites him!

This is what he showed me: Look! The Lord was standing upon a wall that stood straight and true, with a plumb line in his hand.

"Even if they burrow into Sheol, from there my hand will find them. Even if they ascend to the heavens, from there I will bring them down.
