John Wesley on Leviticus 5:7

Not able - Through poverty. And this exception was allowed also in other sin - offerings. For a sin - offering - Which was for that particular sin, and therefore offered first: before the burnt - offering, which was for sins in general; to teach us not to rest in general confessions and repentance, but distinctly and particularly, as far as we can, to search out, and confess, and loath, and leave our particular sins, without which God will not accept our other religious services.
