I am afflicted very much
In a temporal sense, in his body, in his family, and by his enemies; in a spiritual sense, with the corruptions of his heart, with the temptations of Satan, and with the hidings of God's face; and what with one thing or another, he was pressed above measure, and his spirits sunk under the weight of the affliction, so that he was as a dead man; and therefore prays,
quicken me, O Lord, according unto thy word;
(See Gill on Psalms 119:25).
