The earth swallowed them - It is very likely there was also an earthquake on this occasion, and that chasms were made in the bottom of the sea, by which many of them were swallowed up, though multitudes were overwhelmed by the waters, whose dead bodies were afterward thrown ashore. The psalmist strongly intimates that there was an earthquake on this occasion: The voice of thy thunder was in the heaven; the lightnings lightened the world; the Earth Trembled and Shook; Psalm 77:18.

Thou stretchedst out thy right hand,.... That is, exerted his power, and gave a display and proof of it; of which the right hand is an emblem:

the earth swallowed them; meaning Pharaoh and his host; for though they were drowned in the sea, that being a part of the terraqueous globe, they may be said to be swallowed in the earth; as Jonah, when in the depth of the sea, the earth and its bars are said to be about him, Jonah 2:6 and besides, many of Pharaoh's army might be swallowed up in the mud at the bottom of the sea: nor is it improbable that those that were cast upon the banks and sand, whom the Israelites stripped, might be afterwards swallowed up therein.

Thou stretchedst out thy right hand, the earth swallowed them.

15:12 The earth swallowed them - Their dead bodies sunk into the sands on which they were thrown, which sucked them in.

15:1-21 This song is the most ancient we know of. It is a holy song, to the honour of God, to exalt his name, and celebrate his praise, and his only, not in the least to magnify any man. Holiness to the Lord is in every part of it. It may be considered as typical, and prophetical of the final destruction of the enemies of the church. Happy the people whose God is the Lord. They have work to do, temptations to grapple with, and afflictions to bear, and are weak in themselves; but his grace is their strength. They are often in sorrow, but in him they have comfort; he is their song. Sin, and death, and hell threaten them, but he is, and will be their salvation. The Lord is a God of almighty power, and woe to those that strive with their Maker! He is a God of matchless perfection; he is glorious in holiness; his holiness is his glory. His holiness appears in the hatred of sin, and his wrath against obstinate sinners. It appears in the deliverance of Israel, and his faithfulness to his own promise. He is fearful in praises; that which is matter of praise to the servants of God, is very dreadful to his enemies. He is doing wonders, things out of the common course of nature; wondrous to those in whose favour they are wrought, who are so unworthy, that they had no reason to expect them. There were wonders of power and wonders of grace; in both, God was to be humbly adored.
