Jamieson, Fausset & Brown, on Lam 3:29

“Jod. He shall put his mouth in the dust, if so be there may be hope.”

“(Job 42:6). The mouth in the dust is the attitude of suppliant and humble submission to God's dealings as righteous and loving in design (compare Ezr 9:6; Co1 14:25). if so be there may be hope--This does not express doubt as to whether GOD be willing to receive the penitent, but the penitent's doubt as to himself; he whispers to himself this consolation, "Perhaps there may be hope for me."”
