The Lord looses the fettered ones: 8 the Lord gives wisdom (soPHOI) to the blind:
The Lord sets up the broken down: the Lord loves (agaPA) the righteous (diKAIous): the Lord preserves (phyLASsei) the strangers (tous prose-LYtous); 9 he will relieve (anaLE-psetai) the orphan and widow: but will utterly remove the way of sinners. (Brenton LXX)

2 Timothy 3:5b-8--Have nothing to do with such people. 6 They are the kind who worm their way into homes and gain control over gullible women, who are loaded down with sins and are swayed by all kinds of evil desires (epithyMIais), 7 always learning but never able to come to a knowledge of the truth (ale-THEIas). 8 Just as Jannes and Jambres opposed Moses, so also these teachers oppose the truth (anTHIStantai te- ale-THEIa).

Origen (182-254)--To what we have said must be added how the Son is the true vine. Those will have no difficulty in apprehending this who understand, in a manner worthy of the prophetic grace, the saying: "Wine maketh glad the heart of man." For if the heart be the intellectual part, and what rejoices it is the Word most pleasant of all to drink which takes us off human things, makes us feel ourselves inspired, and intoxicates us with an intoxication which is not irrational but divine, that, I conceive, with which Joseph made his brethren merry, then it is very clear how He who brings wine thus to rejoice the heart of man is the true vine. He is the true vine, because the grapes He bears are the truth, the disciples are His branches, and they, also, bring forth the truth as their fruit. It is somewhat difficult to show the difference between the vine and bread, for He says, not only that He is the vine, but that He is the bread of life. May it be that as bread nourishes and makes strong, and is said to strengthen the heart of man, but wine, on the contrary, pleases and rejoices and melts him, so ethical studies, bringing life to him who learns them and reduces them to practice, are the bread of life, but cannot properly be called the fruit of the vine, while secret and mystical speculations, rejoicing the heart and causing those to feel inspired who take them in, delighting in the Lord, and who desire not only to be nourished but to be made happy, are called the juice of the true vine, because they flow from it.

Clementine Homilies (before 350)--And it is by no means that which is true, but that which is pleasing, which persuades every one who seeks to learn from himself. Since, therefore, one thing is pleasing to one, and another to another, one thing prevails over one as truth, and another thing over another. But the truth is that which is approved by the Prophet, not that which is pleasant to each individual. For that which is one would be many, if the pleasing were the true; which is impossible.

John Chrysostom (c.347-407)--but also, what is much greater, "rejoiceth with the truth." "She feels pleasure," saith he, "with them that are well spoken of," as Paul saith, "Rejoice with them that rejoice, and weep with them that weep." (Romans chapter 12, verse 15)

Augustine (354-430)--It is not, then, certain that all men wish to be happy, since those who wish not to rejoice in Thee, which is the only happy life, do not verily desire the happy life. Or do all desire this, but because "the flesh lusteth against the spirit, and the spirit against the flesh," so that they "cannot do the things that they would," they fall upon that which they are able to do, and with that are content; because that which they are not able to do, they do not so will as to make them able? For I ask of every man, whether he would rather rejoice in truth or in falsehood. They will no more hesitate to say, "in truth," than to say, "that they wish to be happy." For a happy life is joy in the truth. For this is joy in Thee, who art "the truth," O God, "my light," "the health of my countenance, and my God." All wish for this happy life; this life do all wish for, which is the only happy one; joy in the truth do all wish for. I have had experience of many who wished to deceive, but not one who wished to be deceived. Where, then, did they know this happy life, save where they knew also the truth? For they love it, too, since they would not be deceived. And when they love a happy life, which is naught else but joy in the truth, assuredly they love also the truth; which yet they would not love were there not some knowledge of it in the memory. Wherefore, then, do they not rejoice in it? Why are they not happy? Because they are more entirely occupied with other things which rather make them miserable, than that which would make them happy, which they remember so little of. For there is yet a little light in men; let them walk -- let them "walk," that the "darkness" seize them not.

Why, then, doth truth beget hatred and that man of thine, preaching the truth become an enemy unto them, whereas a happy life is loved, which is naught else but joy in the truth; unless that truth is loved in such a sort as that those who love aught else wish that to be the truth which they love, and, as they are willing to be deceived, are unwilling to be convinced that they are so? Therefore do they hate the truth for the sake of that thing which they love instead of the truth. They love truth when she shines on them, and hate her when she rebukes them. For, because they are not willing to be deceived, and wish to deceive, they love her when she reveals herself, and hate her when she reveals them. On that account shall she so requite them, that those who were unwilling to be discovered by her she both discovers against their will, and discovers not herself unto them. Thus, thus, truly thus doth the human mind, so blind and sick, so base and unseemly, desire to lie concealed, but wishes not that anything should be concealed from it. But the opposite is rendered unto it, -- that itself is not concealed from the truth, but the truth is concealed from it. Yet, even while thus wretched, it prefers to rejoice in truth rather than in falsehood. Happy then will it be, when, no trouble intervening, it shall rejoice in that only truth by whom all things else are true.
