'Understand' in the Bible

“The ox [instinctively] knows its owner,And the donkey its master’s feeding trough,But Israel does not know [Me as Lord],My people do not understand.”

And He said, “Go, and tell this people:‘Keep on listening, but do not understand;Keep on looking, but do not comprehend.’

“Make the heart of this people insensitive,Their ears dull,And their eyes dim,Otherwise they might see with their eyes,Hear with their ears,Understand with their hearts,And return and be healed.”

They say “To whom would He teach knowledge?And to whom would He explain the message?Those just weaned from milk?Those just taken from the breast?

“As often as it passes through, it will seize you;For morning after morning it will pass through, by day and by night,And it will be sheer terror to understand what it means.”

Stop and take some time and wonder [at this prophecy],Blind yourselves and be blinded [at its fulfillment by your spiritual incompetence].They are drunk, but not from wine;They stagger, but not from strong drink.

The heart (mind) of those who act impulsively will discern the truth,And the tongue of the stammerers will hurry to speak clearly.

You will no longer see the fierce and insolent people,A people of unintelligible speech which no one comprehends,Of a strange and stammering tongue which no one understands.

Now, O Lord our God, save us from his hand so that all the kingdoms of the earth may know and fully realize that You alone, Lord, are God.”

So that they may see and know,And consider and understand together,That the hand of the Lord has done this,That the Holy One of Israel has created it.

“You are My witnesses,” declares the Lord,“And My servant whom I have chosen,That you may know and believe MeAnd understand that I am He.Before Me there was no God formed,And there will be none after Me.

They do not know, nor do they understand, for God has muddied their eyes so that they cannot see, and their hearts (minds) as well so that they cannot understand.

So He will sprinkle many nations [with His blood, providing salvation],Kings will shut their mouths because of Him;For what they had not been told they will see,And what they had not heard they will understand.

And the dogs are greedy; they never have enough.They are shepherds who have no understanding;They have all turned to their own way,Each one to his unlawful gain, without exception.
