Psalms 71:9 - Exposition

Cast me not off in the lime of old age. This expression, combined with the allusion to old age and grey hairs in Psalms 71:18 , indicates that the writer was drawing near to the natural term of human life, and already felt the infirmities of old age creeping upon him. This note of date suits better the time of Adonijah's rebellion than that of Absalom's. Forsake me not when my strength faileth. An appeal to the Divine compassion. If God was his "Rock and Fortress" ( Psalms 71:3 ), his "strong Refuge" ( Psalms 71:7 ), when he was in his full vigour, much more will he support and befriend him when be is weak and helpless.
