Isaiah 41:15, 16: Behold, I will make thee a new sharp, &c

Thee will I wield by grace renew'd,
A weapon for My use design'd:
Go, thou sharp, iron-flail of God,
And thresh the loftiest of mankind.
The stubbornest and strongest beat
With violence of resistless zeal,
And separate from the sacred wheat.
And chase the cursed chaft" to hell:

Dispersed the powers of darkness see:
Thy mountain-sins which reach'd the skies
Wide scatter'd by My breath shall be,
As chaff before the whirlwind flies:
Then shalt thou joyfully confess
My utmost truth, My hallowing word,
The Holy One of Israel praise.
Lost in the glories of thy Lord.
