John Gill's Exposition of the Whole Bible
Psalms 114:3
The sea saw it, and fled,.... When the Word of the Lord appeared at it, as the Targum in the king's Bible; the Red sea, to which the Israelites came when they went out of Egypt; this saw that Judah was the Lord's holy and peculiar people, and that Israel were the subjects of his kingdom; it saw the presence of the Lord among them; it saw him in the glory of his perfections, and felt his power; see
Psalms 77:16, at which its waters fled and parted, and stood up as a wall to make way for Israel to pass through as on dry land,
Exodus 14:21. This was typical of the nations of the Gentile world, comparable to the sea, Daniel 7:2, who saw the work of God going on among them under the ministry of the Gospel in the first times of it, whereby multitudes were turned from idols to serve the living God; this they saw and trembled at, and they and their kings fled for fear; see
Isaiah 41:5, and of the stop put to the ocean of sin in a man's heart, and to the torrent of wickedness that breaks out from thence, by powerful and efficacious grace, much more abounding where sin has abounded.
Jordan was driven back; this was done not at the time of the departure of the Israelites from Egypt, but just before their entrance into the land of Canaan, and in order to it; and being an event similar to the former is here mentioned, and done by the power and presence of God; for as soon as the feet of the priests who bore the ark of the Lord, the symbol of the divine Presence, were dipped in the brim of the waters, the waters below were cut off from those above, and stood up on an heap, and all the Israelites passed through on dry ground, Joshua 3:13, this was an emblem of death, through which the saints pass to glory, which is abolished by Christ, its sting and curse taken away; which when the saints come to, they find it like Jordan driven back, and have an easy and abundant passage through it; and when on the brink of it, and even in the midst of it, sing, "O death, where is thy sting? O grave, where is thy victory?" 1 Corinthians 15:55.
