i.e. I continue praying day and night without intermission. Or thus, I have no silence, i.e. no quietness or rest, as this word signifies, Judges 18:9; in which respect also the sea and waves thereof are said to be silent, i.e. still and quiet, Psalms 107:29 Mark 4:39. And so this last clause answers to and expounds the former, thou hearest not, which is most usual in this book.
