Some translation set quotations from the Old Testament farther to the right on the page than the rest of the text. The ULB does this with the quotations in 3:19 and 3:20.
The Corinthian believers were immature because of their unrighteous actions. He calls them "fleshly," meaning thinking as a nonbeliever. This term is used in opposition to those who are "spiritual." Christians following their "flesh" are foolish and they are following the wisdom of the world.
