# whatever the law says, it speaks to

"everything that the law says people should do is for" or "all the commands that Moses wrote in the law are for" 

# the ones who are under the law

"those who must obey the law"

# so that every mouth may be shut

"so that no people will be able to say anything valid to defend themselves" 

# the whole world held accountable to God

"that God can declare everyone in the world guilty"
