Amos 5:14

(Vers. 14, 15.) Seek good, and not evil, so that you may live, and the Lord God of hosts will be with you as you said: Hate evil, and love good, and establish justice in the gates, perhaps the Lord God of hosts will have mercy on the remnant of Joseph. LXX: Seek good, and not evil, so that you may live, and the Lord God almighty will be with you, as you said: We have hated evil and loved good, and establish justice in the gates, so that the Lord God may have mercy on those who remain from Joseph. You say that God is with you because you are children of Abraham; listen to what follows: If you are Abraham's children, do the works of your father. What are the works of your father Abraham? Love what is good, and not what is evil. It is a great sin, not only to do evil, but also to love it. Many sin, and when the heat of desire is fulfilled, their conscience bites them, and they regret their sin. But there are those who not only do not feel sorry for doing what is evil, but they also boast in their wickedness, fulfilling what is written: When a sinner comes into the depths of impiety, he despises it. Seek good, therefore, and not evil. For if you seek good, in seeking good, you immediately repel evil. However, you would never seek good unless you had first repelled evil, fulfilling the words of the Psalmist saying: Turn away from evil, and do good (Ps. XXXVI, 27). And when you seek good and avoid evil, then you will live in him who says: I am the life (John XIV, 6). He seeks good who believes in him who speaks in the Gospel: I am the good shepherd (Ibid., X, 11). He who flees from evil repels it, of whom it is written: The world is placed in wickedness (1 John 5:16). And in the Lord's Prayer he says: Deliver us from evil (Matthew 6:13). […]

Seek good and not evil, that you may live, and so it will be the Lord God the Almighty with you; in the manner that you said, We have hated evil and loved good, and establish judgment in the gates, so that the Lord God the Almighty may have mercy on the remnant of Joseph. Therefore, in the manner you have spoken, he says, seek good and not evil, so that you may gain well-being by living and being saved, and the Lord God, who has authority over all, may be with you. And establish judgment in the gates, that is, become upright judges; not recording an unjust vote against the weaker; not misrepresenting the power of the just; nor indeed striking the heads of the poor; nor turning aside the way of the humble, so that God may henceforth have mercy on those left from Joseph from the captivities that have already occurred. Therefore, it is necessary to think rightly, and to correct our own minds, so that we must think the things pleasing to God, and achieve virtue, and cling to the ways of justice, and be wise guardians of uprightness; for thus we will have the God of all with us and defending us.

For when a man rules his own self—and that counts for more than to govern others—his heart is in the hand of God, and God turns it where he wills. No wonder if he turns it to the good, perfect goodness is his. And so let us be in the hand of God that we may seek the good, that incorruptible and immutable good of which the prophet Amos says, "Seek good and not evil, that you may live, and so the Lord God almighty will be with you, as you have said, 'We have hated evil and loved good.' " And so, where the good God is, there are the good things that David desired to see and believed that he would see, even as he says, "I believe I shall see the good things of the Lord in the land of the living." They indeed are the good things that endure always, that cannot be destroyed by change of time or of age.

And so, where the good God is, there are the good things that David desired to see and believed that he would see, even as he says, "I believe I shall see the good things of the Lord in the land of the living.(Ps. 27:13)"' They indeed are the good things that endure always, that cannot be destroyed by change of time or of age.

It was the old custom that the elders should sit at the gate to make out by judicial trial the quarrels of persons at strife, in order that they should never enter the city at variance and should dwell there in harmony. And hence the Lord says by the prophet, "Establish judgment at the gate."
