Matthew 26:72: Atid again he denied with an oath

Who weakly once to sin gives place,
Left to himself, by Jesus' grace
No longer now withheld,
Assail'd by sin's redoubled power,
His abject soul resists no more,
Or only fights to yield.

When rash into the snare we run,
One sin will draw a second on.
And to a third increase:
Fresh guilt chastises for the past
Till quite forsook we rise at last
To blackest perjuries.
