Forgetfulness
Hastings' Dictionary of the Bible [1]
Forgetfulness . Psalms 88:12 ‘Shall thy wonders be known in the dark? and thy righteousness in the land of forgetfulness?’ The meaning is general, as Coverdale ‘the londe where all thinges are forgotten,’ but probably more passive than active, that the person is forgotten rather than that he forgets. So Wis 17:3; but in Wis 14:26; Wis 16:11 , Sir 11:25 the word expresses the tendency to forget.
