'Corner' in the Bible

therefore thus saith the Lord Jehovah, Behold, I lay in Zion for a foundation a stone, a tried stone, a precious corner -'stone of sure foundation: he that believeth shall not be in haste.

And though the Lord give you the bread of adversity, and the water of affliction, yet shall not thy teachers be removed into a corner any more, but thine eyes shall see thy teachers:

“I have not spoken in secret,In a corner of a land of darkness;I did not say to the descendants of Jacob,‘Seek Me in vain [with no benefit for yourselves].’I, the Lord, speak righteousness [the truth—trustworthy, a straightforward correlation between deeds and words],Declaring things that are upright.
