'Closed' in the Bible

Their fat they have closed up, Their mouths have spoken with pride:

In my distress [when I seemed surrounded] I called upon the LordAnd cried to my God for help;He heard my voice from His temple,And my cry for help came before Him, into His very ears.

For dogs have surrounded me;a gang of evildoers has closed in on me;they pierced my hands and my feet.

I proclaim righteousness in the great assembly;see, I do not keep my mouth closed—as You know, Lord.

Has God forgotten to have compassion? Or has he closed off his mercies in anger? Selah

They have surrounded me like flood waters all day long;They have completely encompassed me.

Therefore the earth opened and swallowed Dathan,And engulfed the company of Abiram.
