Genesis 42:21: How often, Lord, hath trouble brought

How often, Lord, hath trouble brought
My long-forgotten sins to mind!
And by this fresh affliction taught,
I tremble at the woes behind:
But while I guilty, guilty plead,
O do not from Thy presence cast,
Nor leave me at my greatest need,
To perish in my sins at last.

Ah! rid me of this fear and doubt,
Doubt that I shall not persevere,
Fear that my sin will find me out,
And plague with all Thy judgments here.
Jesus, whom I to death have sold;
My guilty burden to remove.
Tell me. Thou hast redeem'd of old,
And save me by Thy dying love.
