(V. 4, seqq.) Listen to this, you who crush the poor and make the needy of the earth fail, saying: When the month passes, we will sell our goods, and on the Sabbath, we will open the granary to decrease the measure and increase the weight; we will use deceitful scales to possess the poor in silver and sell the refuse of wheat. LXX: Listen to this, you who crush the poor in the morning and oppress the needy from the land, saying: When the month passes, we will trade and on the Sabbath, we will open the granary to make the measure smaller and the weight greater; we will use dishonest scales to possess the poor in money and the needy for shoes, and we will engage in every sale. Let the hook of the apples not appear in vain, and let the vessel of the bird catcher be shown, and through these things, the impending captivity is briefly described as the cause of offense to God. Oh, you Juda, oh you Israel, hear the crimes you have committed, rising in the night, for prayer and hymns to God: you have the zeal to oppress or crush the poor, so that they, consumed by hunger and poverty, may be taken from the land. You who wait for the new moon to engage in business, and increase interest on loans, and open your storehouses on the Sabbath, and give more grain in return, and turn the sacred festivals of God into sordid profits for your own gain: you who make the measure smaller when selling goods, and use heavier weights when receiving, and use unfair scales in order to possess the money of the poor, and hold people in such low regard that you fulfill what was said above about you: Because you sold the just for silver, and the poor for shoes: you have leaped into such greed for profit that you sell to the poor not the grain which sustains human bodies, but the refuse and chaff of the grain, mixing dust and bran. Indeed, we sometimes see even perverse teachers and rulers, who dominate the clergy without the fear of God, of whom Jeremiah speaks: Their shepherds have not benefited them (Jer. XII, 13, LXX), making a profit out of piety. They sit in the temple like moneychangers, not in cages but in seats as if they were masters, selling the gifts of the Holy Spirit. They give a smaller and larger measure to the poor, either too little or nothing at all, but to the rich and those from whom they seek profit, they speak with lengthy sermons like preachers. And for the sake of money, they crush the heads of the poor and trample on them, not offering them the Lord's grain that strengthens the heart of man, but rather feeding them scraps and the cheapest dust with eager mouths. They even sell things that are worthless, despite the fact that the Lord commanded his apostles, 'Freely you have received, freely give' (Matt. X, 8).
