Psalm 78:51; Psalm 105:36; Psalm 111:10

51 And smote all the firstborn in Egypt; the chief of their strength in the tabernacles of Ham:
36 He smote also all the firstborn in their land, the chief of all their strength.
10 The fear of the LORD is the beginning of wisdom: a good understanding have all they that do his commandments: his praise endureth for ever.
