Cast me not off in the time of old age; forsake me not when my strength faileth.
Ver. 9. Cast me not off in the time of old age] For now I have most need of thee. The white rose is soonest cankered, so is the white head soonest corrupted.
Saepe nigrum cor est, caput album -
Satan maketh a prey of old Solomon, Asa, Lot, others; whom when young he could never so deceive. The heathens, therefore, well warn us to look well to our old age, as that which cometh not alone, but is infested with many diseases both of body and mind. This David knew, and therefore prayed, as here, "Cast me not off in the time of old age; forsake me not when my strength faileth." He is a rare old man that can say with Caleb, Joshua 14:10,11. Omnia fert aetas, animum quoque.
