Psalm 69:15: ToPHET its mouth hath open'd wide

ToPHET its mouth hath open'd wide,
To swallow up my soul;
And still I on the brink abide
Of the sulphureous pool.
O let Thy mercy interpose,
While on the brink I stay;
And suffer not the pit to close
Its mouth upon its prey.

The inextinguishable fire
Kindled in me I feel;
And never was a sinner nigher,
Yet not shut up in hell.
As scorch'd I call on Jesu's name,
Thou dying Lamb of God;
No water can assuage the flame, —
O quench it in Thy blood!
