The Message (MSG)
6-7 God spoke to Cain: "Why this tantrum? Why the sulking? If you do well, won't you be accepted? And if you don't do well, sin is lying in wait for you, ready to pounce; it's out to get you, you've got to master it."
Common English Bible (CEB)
7 If you do the right thing, won't you be accepted? But if you don't do the right thing, sin will be waiting at the door ready to strike! It will entice you, but you must rule over it."
New Life Version (NLV)
7 Will not your face be happy if you do well? If you do not do well, sin is waiting to destroy you. Its desire is to rule over you, but you must rule over it."
Young's Literal Translation (YLT)
7 Is there not, if thou dost well, acceptance? and if thou dost not well, at the opening a sin-offering is crouching, and unto thee its desire, and thou rulest over it.'
New Century Version (NCV)
7 If you do things well, I will accept you, but if you do not do them well, sin is ready to attack you. Sin wants you, but you must rule over it."
