But, Thomas, one of the twelve, the one called Didymus, was not with them when Jesus came.

lo! I am placing a woollen fleece, on the threshing-floor, - if, dew, be on the fleece alone and, on all the ground, it be dry, then shall I know that thou wilt bring salvation, by my hand, unto Israel, as thou hast spoken. And it was so, and he rose up early, on the morrow, and pressed together the fleece, - and wrung out the dew from the fleece, a small bowl full of water. Then said Gideon unto God, Let not thine anger kindle upon me, but let me speak, only this once, - Let me, I pray thee, put to the proof, only this once, with the fleece, I pray thee, let it be dry on the fleece alone, while, on all the ground, there be dew.read more.
And God did so on that night, - and it was dry on the fleece alone, while, on all the ground, there was dew.

They bring him unto the Pharisees - him at one time blind. Now it was Sabbath, on the day when Jesus made, the clay, and opened his eyes. Again, therefore, the Pharisees also questioned him, as to how he received sight. And, he, said unto them - Clay, laid he upon mine eyes, and I washed, - and do see.read more.
Certain from among the Pharisees, therefore, were saying - This man is not, from God, because, the Sabbath, he keepeth not. Others, howeverwere saying - How can a sinful man, such signs as these, be doing? And there was, a division, among them. So they were saying unto the blind man, again, What dost, thou, say concerning him, in that he opened thine eyes? And, he, said - A prophet, is he. The Jews, therefore, did not believe, concerning him, that he was blind, and received sight, - until they called the parents of him that had received sight, and questioned them, saying - Is, this, your son, of whom, ye, say, that blind, he was, born? How, then, seeth he, even now? His parents, therefore, answered, and said - We know that, this, is our son, and that, blind, he was born; But, how he now seeth, we know not, or, who opened his eyes, we, know not, - Question, him, he is, of age, he, concerning himself, shall speak. These things, said his parents, because they were in fear of the Jews, - for, already, had the Jews agreed together, that, if anyone should confess, him, to be Christ, an, excommunicant from the synagogue, should he be made. For this cause, his parents said - He is, of age, - question him. So they called the man a second time - him who had been blind, and said unto him - Give glory unto God! We know that, this man, is, a sinner. He, therefore, answered - Whether he is a sinner, I know not: One thing, I know, - That, whereas I was, blind, now, I see! They said, therefore, unto him - What did he unto thee? How opened he thine eyes? He answered them - I told you just now, and ye did not hear: Why, again, do ye wish to hear? Are, ye also, wishing to become, his disciples? And they reviled him, and said - Thou, art, the disciple, of that man; but, we, are, Moses', disciples: - We, know, that, unto Moses, hath God spoken; but, as for this man, we know not whence he is. The man answered, and said unto them - Why! Herein, is, the marvel: That, ye, know not whence he is, and yet he opened mine eyes. We know that, God, unto sinners, doth not hearken: but, if one be, a worshipper of God, and be doing, his will, unto this one, he hearkeneth. Out of age-past time, hath it never been heard, that anyone opened the eyes of one who, blind, had been born. If this man were not from God, he could have done nothing. They answered and said unto him - In sins, wast, thou, born, altogether; and art, thou, teaching, us? And they cast him out. Jesus heard that they had cast him out: and, finding him, said - Dost, thou, believe on the son of Man? He answered and said- And, who, is he, Sir, that I may believe on him? Jesus said unto him - Thou hast both seen him and, he that is speaking with thee, is, he. And, he, said - I believe, Sir! and worshipped him. And Jesus said - For judgment, I, unto this world, came: that, they who were not seeing, might see, and, they who were seeing, might become, blind. They of the Pharisees who were with him, heard, these things, and said unto him - Are, we also, blind? Jesus said unto them - If, blind, ye had been, ye had not had sin; but, now, ye say, We see, your sin, abideth.

And, having arranged with him a day, there came unto him, to the lodging, a larger number; unto whom he proceeded to expound, bearing full witness as to the kingdom of God, and persuading them concerning Jesus, both from the law of Moses, and from the prophets, - from morning till evening. And, some, indeed, were persuaded by the things that were spoken, whereas, others, disbelieved;read more.
and, not being, agreed, among themselves, they began to leave, - Paul having said one thing - Well, did, the Holy Spirit, speak through Isaiah the prophet, unto your fathers, saying - Go thy way unto this people, and say - Ye shall, surely hear, and yet will in nowise understand. And, surely see, and yet will in nowise perceive; For the heart of this people, hath become dense, and, with their ears, heavily, have they heard, and, their eyes, have they closed, - lest once they should see with their eyes, and, with their ears, should hear, and, with their hearts, should understand, and return, - when I would certainly heal them. Be it, known unto you, therefore, that, unto the nations, hath been sent forth this salvation of God: they, will also hear.
