Jer 17:6

“A person who relies on himself, however, or even on the person whose duty it is to provide for his needs, and thinks that his own activity or that of his associate is a sufficient resource for his livelihood runs the risk, as he places his hope in humankind, of falling under the curse that reads, "Cursed is the one that trusts in humankind and makes flesh his arm and whose soul departs from the Lord." Now, by the words "that trusts in humankind" the Scripture forbids a person to place his hope in another, and by the words "and makes flesh his arm" it forbids him to trust in himself. Either course is termed a defection from the Lord. Further, in adding the final issue of both, "He shall be like tamarisk in the desert, and he shall not see when good shall come," the Scripture declares that for anyone to place his trust either in himself or in anyone else is to alienate himself from the Lord.”

“One thing you must flee, sin. One refuge from evil must be sought, God. Do not trust in princes. Do not be exalted in the uncertainty of wealth. Do not be proud of bodily strength. Do not pursue the splendor of human glory. None of these things save you. All are transient. All are deceptive. There is one refuge: God. "Cursed is the one who trusts in humankind" or in any human thing.”

“One who puts his trust in humankind or is buoyed up by some other concerns of life, such as power or possessions or any of the things considered by the many to be glorious, is not able to say, "O Lord my God, in you have I put my trust." In fact, there is a command that we should not put our trust in rulers, and "cursed is the one who trusts in humankind." As it is proper not to worship anything else besides God, so also is it proper not to trust in any other except God the Lord of all things. "The Lord," it is said, "is my hope and my praise."”

“It is not only the one who puts his hope in humankind that is accursed, but also the one who uses the flesh of his arm, that is, his strength and all that he does, not for the Lord of mercy but so that power will be thought to have come from him. For whoever does this withdraws his heart from the Lord by claiming himself to be capable when he is not capable. He will also be like the tamarisk in the desert, which, in Hebrew, is called an aroher, or, as translated by Symmacus, a fruitless plant, nor will he see goodness when it arrives and is seen by the multitude of nations, but he will live in a wasteland. All this is said about the Jewish people, who live in a desert and do not bear fruit and are located in an uninhabited salt land that produces no fruit and is a host neither to God, nor to the army of angels, nor to the grace of the Holy Spirit nor to the knowledge of teachers.”
