Lowell Mason (1792–1872)

In mercy, Lord, remember me,
Through all the hours of night,
And grant to me most graciously
The safeguard of Thy might.

With cheerful heart I close mine eyes,
Since Thou wilt not remove;
O in the morning let me rise
Rejoicing in Thy love.

Or if this night should prove my last,
And end my transient days,
Lord, take me to Thy promised rest,
Where I may sing Thy praise.
