'Understandeth' in the Bible

They are all plain to him that understandeth, and right to them that find knowledge.

A scorner seeketh wisdom, and findeth it not: but knowledge is easy unto him that understandeth.

A scorner smite, and the simple acts prudently, And give reproof to the intelligent, He understandeth knowledge.

From Jehovah are the steps of a man, And man -- how understandeth he his way?

When thou sayest, 'Lo, we knew not this.' Is not the Ponderer of hearts He who understandeth? And the Keeper of thy soul He who knoweth? And He hath rendered to man according to his work.

The righteous knoweth the plea of the poor, The wicked understandeth not knowledge.

A servant is not corrected by words: he understandeth indeed, but he will not answer.
