1 Thessalonians 4:6-8

Twentieth_Century(i) 6 None of you over-reaching or taking advantage of his Brother in such matters. 'The Lord takes vengeance' upon all who do such things, as we have already warned you and solemnly declared. 7 For God's Call to us does not permit of an impure life, but demands purity. 8 Therefore he who disregards this warning disregards, not man, but God who gives you his Holy Spirit.
