No heart can conceive, and no tongue can declare,
How precious to Israel the blood did appear;
When God in His mercy did pass each house o’er
With blood on the lintel and posts of the door.

Destruction in Egypt most fearfully spread,
Till the firstborn of all the Egyptians were dead.
Lamentation and wailing for those that are not,
At midnight are heard from the palace and cot.

But Israel beneath the blood-guarded roof,
In peaceful repose, from destruction aloof,
Enjoys, though surrounded with terror abroad,
Both refuge and calm through the sign of the blood.

An emblem is this of the blood of the cross,
Beneath it no sinner can e’er suffer loss,
When taught by the Spirit for pardon to fly,
Though vile as Manasseh, or Mary, or I.
