'Understand' in the Bible

Jehovah looked down from heaven upon the children of men, To see if there were any that did understand, That did seek after God.

God looked down from heaven upon the children of men, To see if there were any that did understand, That did seek after God.

They know not, neither do they understand; They walk to and fro in darkness: All the foundations of the earth are shaken.

A brutish man knoweth not; Neither doth a fool understand this:

Make me to understand the way of thy precepts: So shall I meditate on thy wondrous works.

I understand more than the aged, Because I have kept thy precepts.
