William Cowper (26 November 1731 – 25 April 1800 / Hertfordshire)

Gracious Lord, our children see,
By Thy mercy we are free;
But shall these, alas! remain
Subjects still of Satan's reign?
Israel's young ones, when of old
Pharaoh threaten'd to withhold,
Then Thy messenger said, "No;
Let the children also go!"
