ECC 9:2

2 [But we know that some time in the future] we will all die; it does not matter whether we act righteously or wickedly, whether we are good or whether we are bad, whether we are acceptable for [worshiping God] or whether [we have done things to cause us to be] unacceptable; it does not matter if we offer sacrifices [to God] or if we do not; it does not matter if we do what we have promised God that we will do or if we do not; [we all die]. The same thing will happen to good people and to sinful people, to those who solemnly promise [to do things for God] and to those who are afraid to make such promises.
