Mark 7: We ought to wash before we eat

We ought to wash before we eat
We should our former sins confess,
Who oft have snatch'd the' unhallow'd meat,
Indulged our nature's greediness,
And feeding without fear or thought
Ungratefully our God forgot.

This filth we first should purge away
In Jesus' all-atoning blood,
For pardon, and His Spirit pray
To bless and sanctify our food,
And then the gift of God partake
Vouchsafed us for our Saviour's sake.
