42. Such, indeed, is the truth of unity that, when the nature alone of human birth or of human flesh is indicated, one man is the term used for the many, as it is written: “The Lord is my helper, I will not fear what man can do unto me;” Ps. cxviii. 6. that is, not the one person of a man, but the one flesh, the one frailty of human birth. It added also: “It is better to trust in the Lord than to trust in man.” Ps. cxviii. 8. Here, too, it did not denote one particular man, but a universal condition. Then, immediately after it added, speaking of many: “It is better to put confidence in the Lord than to put confidence in princes.” Ps. cxviii. 9. Where man is spoken of, as we have already said, there the common unity of the nature, which exists between all is indicated; but where the princes are mentioned, there is a certain distinction between their different powers.
