Yashaw’yahu (Isaiah) 6:8-10 And I heard the voice of YAHUAH, saying, “Whom do I send, and who would go for Us?” And I said, “Here am I! Send me.” (9) And He said, “Go, and you shall say to this people, ‘Hearing, you hear, but do not understand; and seeing, you see, but do not know.’ (10) “Make the heart of this people fat, and their ears heavy, and shut their eyes; lest they see with their eyes, and hear with their ears, and understand with their heart, and shall turn and be healed.”
Yashaw’yahu (Isaiah) 42:17-20 “Those who trust in idols, who say to the moulded images, ‘You are our mighty ones,’ shall be turned back, utterly ashamed. (18) “Hear, you deaf! And look, you blind, and see. (19) “Who is blind but My servant, or deaf as My messenger whom I send? Who is blind as he who is at peace, and blind as servant of YAHUAH? (20) “You see much, but do not observe; ears are open, but do not hear.”
Yashaw’yahu (Isaiah) 44:6-20 “Thus said YAHUAH, Sovereign of Yashur’al, and his Redeemer, YAHUAH of hosts, ‘I am the First and I am the Last, besides Me there is no Aluahim. (7) ‘And who is like Me? Let him call and declare it, and lay it before Me, since I appointed the everlasting people. And the events that are coming and those that do come, let them declare these to them. (8) ‘Do not fear, nor be afraid. Have I not since made you hear, and declared it? You are My witnesses. Is there an Aluah besides Me? There is no other Rock, I know not one.’ ” (9) Those who make an idol, all of them are emptiness, and their delights do not profit. And they are their own witnesses; they neither see nor know, so that they are put to shame. (10) Who would form a mighty one or cast an idol that is of no value? (11) See, all his companions are ashamed, and the workmen, they are but men. Let them all be gathered together, let them stand up, let them fear, let them be put to shame, altogether. (12) The craftsman in iron with the tools works one in the coals, and fashions it with hammers, and works it with the strength of his arms. Even so, he shall be hungry, and has no strength; he drinks no water and is weary. (13) The carpenter stretches out his rule, he outlines it with chalk; he fashions it with a plane, and he outlines it with the compass, and makes it like the figure of a man, according to the comeliness of a man, to remain in the house. (14) He cuts down cedars for himself, and takes cypress and oak, which he raised among the trees of the forest. He has planted a pine, and the rain nourishes it. (15) And it shall be for a man to burn, for he takes some of it and warms himself. He also kindles it and shall bake bread. He also makes a mighty one and bows himself to it – has made it a carved image and falls down before it. (16) Half of it he shall burn in the fire; with this half he eats meat. He roasts a roast, and is satisfied. He also warms himself and says, “Aha, I am warm, I have seen the fire.” (17) And the rest of it he makes into a mighty one, his carved image. He falls down before it and worships, prays to it and says, “Deliver me, for you are my mighty one.” (18) They do not know nor understand, for He has smeared their eyes from seeing, and their hearts from understanding. (19) And no one recalls it to his heart, nor is there knowledge nor understanding to say, “I have burned half of it in the fire, and I have also baked bread on its coals; I have roasted meat and eaten it. And shall I make the rest of it an abomination? Should I fall down before a log of wood?” (20) Feeding on ashes, a deceived heart turns him aside, and he does not deliver his being, nor says, “Is there not a lie in my right hand?”
Matatyahu 13:10-15 And the taught ones came and said to Him, “Why do You speak to them in parables?” (11) And He answering, said to them, “Because it has been given to you to know the secrets of the reign of the heavens, but to them it has not been given. (12) “For whoever possesses, to him more shall be given, and he shall have overflowingly; but whoever does not possess, even what he possesses shall be taken away from him. (13) “Because of this I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand. (14) “And in them the prophecy of Yashaw’yahu is completely filled, which says, ‘Hearing you shall hear and by no means understand, and seeing you shall see and by no means perceive, (15) for the heart of this people has become thickened, and their ears are hard of hearing, and their eyes they have closed, lest they should see with their eyes and hear with their ears, lest they should understand with their heart, and turn back, and I heal them.’
Matatyahu 23:16-26 “Woe to you, blind guides, who say, ‘Whoever swears by the Dwelling Place, it does not matter, but whoever swears by the gold of the Dwelling Place, is bound by oath.’ (17) “Fools and blind! For which is greater, the gold or the Dwelling Place that sets the gold apart? (18) “And, ‘Whoever swears by the altar, it does not matter, but whoever swears by the gift that is on it, is bound by oath.’ (19) “Fools and blind! For which is greater, the gift or the altar that sets the gift apart? (20) “He, then, who swears by the altar, swears by it and by all that is upon it. (21) “And he who swears by the Dwelling Place, swears by it and by Him who is dwelling in it. (22) “And he who swears by the heaven, swears by the throne of Aluahim and by Him who is sitting upon it. (23) “Woe to you, scribes and Pharisees, hypocrites! Because you tithe the mint and the anise and the cumin, and have neglected the weightier matters of the Turah: the right-ruling and the compassion and the belief. These need to have been done, without neglecting the others. (24) “Blind guides – straining out a gnat and swallowing a camel! (25) “Woe to you, scribes and Pharisees, hypocrites! Because you clean the outside of the cup and dish, but inside they are filled with plunder and unrighteousness. (26) “Blind Pharisee, first clean the inside of the cup and dish, so that the outside of them becomes clean too.”
Yahuchanan (John) 3:16-21 “For Aluahim so loved the world that He gave His only brought-forth Son, so that everyone who believes in Him should not perish but possess everlasting life. (17) “For Aluahim did not send His Son into the world to judge the world, but that the world through Him might be saved. (18) “He who believes in Him is not judged, but he who does not believe is judged already, because he has not believed in the Name of the only brought-forth Son of Aluahim. (19) “And this is the judgment, that the light has come into the world, and men loved the darkness rather than the light, for their works were wicked. (20) “For everyone who is practicing evil matters hates the light and does not come to the light, lest his works should be exposed. (21) “But the one doing the truth comes to the light, so that his works are clearly seen, that they have been wrought in Aluahim.”
Yahuchanan (John) 12:35-40 YAHUSHUA, therefore, said to them, “Yet a little while the light is with you. Walk while you have the light, lest darkness overtake you. And he who walks in darkness does not know where he is going. (36) “While you have the light, believe in the light, so that you become sons of light.” These words YAHUSHUA spoke, and went off and was hidden from them. (37) But though He had done so many signs before them, they did not believe in Him, (38) that the word of Yashaw’yahu the prophet might be filled, which he spoke, “YAHUAH, who has believed our report? And to whom has the arm of YAHUAH been revealed?” (39) Because of this they were unable to believe, because again Yashaw’yahu said: (40) “He has blinded their eyes and hardened their heart, so that they should not see with their eyes and understand with their heart, and turn, and I should heal them.”
Romans 11:7-8 What then? Yashur’al has not obtained what it seeks, but the chosen did obtain it, and the rest were hardened. (8) As it has been written, “YAHUAH has given them a spirit of deep sleep, eyes not to see and ears not to hear, unto this day.”
1 Yahuchanan (John) 2:7-11 Beloved, I write no fresh command to you, but an old command which you have had from the beginning. The old command is the Word which you heard from the beginning. (8) Again I write you a fresh command, which is true in Him and in you, because the darkness is passing away, and the true light now shines. (9) The one who says he is in the light, and hates his brother, is in the darkness until now. (10) The one who loves his brother stays in the light, and there is no stumbling-block in him. (11) But the one who hates his brother is in the darkness and walks in the darkness, and does not know where he is going, because the darkness has blinded his eyes.
Note: Please also read Yahuchanan (John) Chapter 9 in its entirety. It relates the story of how a blind man was healed, and how the Pharisees condemned him and rejected the One Who healed him.
