In the dark; in the grave, which is called the land of darkness, Job_10:21,22.
In the land of forgetfulness; in the grave; so called, either, first, Actively, because there men forget and neglect all the concerns of this life, being indeed but dead carcasses without any sense or remembrance. Or rather, secondly, Passively, because there men are forgotten not only by men, as is noted, Job_24:20Psa_31:12, but by God himself, as he complained, Psa_88:5.
