Psalms 102:11 - Exposition

My days are like a shadow that declineth ; literally, that lengthens, as shadows do when the day declines (comp. Psalms 102:24 ). The psalmist, like his nation, is old before his time; the shades of evening have come upon him, when he should have been in his midday brightness. And I am withered like grass (comp. Psalms 102:4 ). The "I" here is emphatic ( אני )—not only is the psalmist's heart withered, but he himself is altogether scorched and dried up.
