King James Version

4 For we that are in this tabernacle do groan, being burdened: not for that we would be unclothed, but clothed upon, that mortality might be swallowed up of life.

New International Version

4 For while we are in this tent, we groan and are burdened, because we do not wish to be unclothed but to be clothed instead with our heavenly dwelling, so that what is mortal may be swallowed up by life.

New Living Translation

4 While we live in these earthly bodies, we groan and sigh, but it’s not that we want to die and get rid of these bodies that clothe us. Rather, we want to put on our new bodies so that these dying bodies will be swallowed up by life.

Contemporary English Version

4 These tents we now live in are like a heavy burden, and we groan. But we don't do this just because we want to leave these bodies that will die. It is because we want to change them for bodies that will never die.

Young's Literal Translation

4 for we also who are in the tabernacle do groan, being burdened, seeing we wish not to unclothe ourselves, but to clothe ourselves, that the mortal may be swallowed up of the life.
