Exodus 15:12

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.
