Note: this unique psalm begins and ends with giving thanks but the main section is  linear, recounting the mighty hand of God in delivering Israel from Egypt and bringing them to the land beyond Jordan. The forty year wilderness experience is covered in just one verse! The final section appears to reflect on recent deliverance. So why is the creation of the heavens (as distinct from creation of all things) and then the smiting of Egypt and Sihon/Og so prominent in the psalm? Is it because the plagues of Egypt and the defeat of the giants (e.g. Og) was directed against the mythology of Gentile gods believed to sit in the heavens?

A. O give thanks

C. Delivered Israel from Egypt
10 To him that smote Egypt in their firstborn:

12 With a strong hand, and with a stretched out arm:
for his mercy endureth for ever.

D. Divided the Red Sea
13 To him which divided the Red sea into parts:

25 Who giveth food to all flesh:
for his mercy endureth for ever.
