Salmi 31:10

For my life is spent with grief, and my years with sighing: my strength faileth because of mine iniquity, and my bones are consumed.

For my life ... grief - (Geremia 20:18.)

My strength ... iniquity. The Psalmist's infirmities and occasional grievous transgressions, through neglect of watchfulness, brought on him chastisement from the Lord, executed by his enemies (Salmi 38:4). Though, in relation to the Lord, he felt that his sin justly incurred the punishment, yet, in relation to them whose whole course was estranged from God, he could justly claim God's interposition in his behalf, on the ground of God's righteousness, since the general tenor of his life was that of a sincere servant of God.

Bones ... consumed - i:e., lose their strength.
