[11:8] 1 tn The phrase “the days of darkness” refers to the onset of old age (Eccl 12:1-5) and the inevitable experience of death (Eccl 11:7-8; 12:6-7). Elsewhere, “darkness” is a figure of speech (metonymy of association) for death (Job 10:21-22; 17:13; 18:18).
[11:8] 2 tn The term הֶבֶל (hevel) here means “obscure,” that is, unknown. This sense is derived from the literal concept of breath, vapor or wind that cannot be seen; thus, the idea of “obscure; dark; difficult to understand; enigmatic” (see HALOT 236–37 s.v. I הֶבֶל; BDB 210–11 s.v. I הֶבֶל). It is used in this sense in reference to enigmas in life (6:2; 8:10, 14) and the future which is obscure (11:8).
