Heb Hebrews, chapter Epistle to the Hebrews, chapter 3
Beware that you do not stop trusting in Christ.
Hebrews 3:12-15
Instead, each of you must encourage each other every day, while you still have the opportunity [IDM], in order that none of you may stubbornly reject God by letting others deceive you (OR, as you deceive yourselves), with the result that you (sg) sin [PRS].
