2:6 bottoms of the mountains. In Jonah’s day, so far as we know, men had no means to explore the sea floor, yet Jonah somehow knew that mountains had “roots” extending deep into the earth’s crust. In fact, this may even be another way of referring to his descent into “hell.”

2:6 corruption. The Lord Jesus Christ, speaking prophetically through David, had prophesied His resurrection, saying: “Thou wilt not leave my soul in hell; neither wilt thou suffer thine Holy One to see corruption” (Psalm 16:10). Jonah used the same word here, indicating still further the remarkable typological correlation of his own experience to the death and resurrection of Christ, as cited by Him (Matthew 12:40).
