KJV Verse: 

Mat 22:29 Ye do err, not knowing the scriptures, nor the power of God.

Greek Verse: 

Literal Alternative: 

You lead yourselves astray, not wanting to examine the writings nor the capability of God.

Hidden Meaning: 

The verse was the precurson of Shakespeare's, "There are more things in heaven and earth than are dreamt of in your philosophy." Christ's challengers here assume that the afterlife is like this life.

"Err" is from a verb that means "to cause to wander", "to lead astary", "to mislead", "to wander", "to stray," and "to be misled." It is in a form where the subject acts on themselves, so "you lead yourself astray."

The negative used here is the Greek negative of a subjective opinion. The sense is that "you don't want" to do something or "don't think" something.

The word translated as "know" means primarily "to see" and is used to mean "know' as we use the word "see" to mean "know" in English. It is in the forming of an adjective, "knowing."

"Scripture" is from a very general noun that "representing by means of lines", "a drawing," "writing," and "that which is written." It is in the plural, so something like "the writings." It came to mean "scripture" from its use in the Gospels.

"Power" is from a word that describes abilities and capacities, what actions a person can do or has done so "power", "might", "influence", "authority," and "force." It does not carry the sense of authority over others, either people or laws.
