Exodus 15:13 - Joseph Benson’s Commentary on the Old and New Testaments

Thou in thy mercy, &c. This and the four following verses contain a prophetic declaration of the glorious protection which God would grant his people after having brought them out of Egypt. And the reader does not know which to admire most, God's tenderness for his people, whose guide and conductor he himself will be; or his formidable power, which, by causing terror and dread to walk before it, freezes with fear all such nations as should presume to oppose the passage of the Israelites through the Red sea, and strikes those nations, so that they become motionless as a stone; or, lastly, God's wonderful care to settle them in a fixed and permanent manner in the promised land, or rather to plant them in it, an emphatic expression, and which alone recalls to mind all that the Scriptures observe, in so many places, concerning the care which God has taken to plant his beloved vine, to water it, to enclose it with fences, and to multiply and extend its fruitful branches to a great distance.
