A voice says, “Call out [prophesy].”Then he answered, “What shall I call out?”[The voice answered:] All humanity is [as frail as] grass, and all that makes it attractive [its charm, its loveliness] is [momentary] like the flower of the field.

Thus says the Lord,“Cursed is the man who trusts in and relies on mankind,Making [weak, faulty human] flesh his strength,And whose mind and heart turn away from the Lord.

But we have this precious treasure [the good news about salvation] in [unworthy] earthen vessels [of human frailty], so that the grandeur and surpassing greatness of the power will be [shown to be] from God [His sufficiency] and not from ourselves.

For the Law appoints men as high priests who are weak [frail, sinful, dying men], but the word of the oath [of God], which came after [the institution of] the Law, permanently appoints [as priest] a Son who has been made perfect forever.
