A brief reading from John Calvin's Commentary on Psalm 105:26-30.

KJV

26 He sent Moses his servant; and Aaron whom he had chosen.

27 They shewed his signs among them, and wonders in the land of Ham.

28 He sent darkness, and made it dark; and they rebelled not against his word.

29 He turned their waters into blood, and slew their fish.

30 Their land brought forth frogs in abundance, in the chambers of their kings.
