Psalms 136:10

To him that smote Egypt in their firstborn: for his mercy endureth for ever:

To him who struck down the Egyptian firstborn; For his loving kindness endures forever;

To him that smote Egypt in their first-born; For his lovingkindness `endureth' for ever;

To Him smiting Egypt in their first-born, For to the age `is' His kindness.

He struck down the firstborn of Egypt His loving devotion endures forever.
