Show us thy mercy - Blot out all our sins.
And grant us thy salvation - Give us such a complete deliverance as is worthy of thy majesty and mercy to bestow!
Shew us thy mercy, O Lord - That is, Manifest thy mercy in returning to us; in forgiving our sins; in taking from us the tokens of thy displeasure.
And grant us thy salvation - Salvation or deliverance from our present trouble and calamities.
