1 Corinthians 10 v 23-24


1 Corinthians 10:23-24 
(23)  All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not. 
(24)  Let no man seek his own, but every man another's wealth. 


10:23-24. The principle of freedom (everything is permissible; cf. 6:12) was to be regulated by love for others. Activities that are not beneficial or constructive or that do not promote the good of others (cf. 10:33) should be avoided.
