Exodus 15:1-21: "1 Then Moses and the people of Israel sang this song to the LORD, saying, 'I will sing to the LORD, for he has triumphed gloriously; the horse and his rider he has thrown into the sea. 2 The LORD is my strength and my song, and he has become my salvation; this is my God, and I will praise him, my father's God, and I will exalt him. 3 The LORD is a man of war; the LORD is his name.
"'4 Pharaoh's chariots and his host he cast into the sea, and his chosen officers were sunk in the Red Sea. 5 The floods covered them; they went down into the depths like a stone. 6 Your right hand, O LORD, glorious in power, your right hand, O LORD, shatters the enemy. 7 In the greatness of your majesty you overthrow your adversaries; you send out your fury; it consumes them like stubble. 8 At the blast of your nostrils the waters piled up; the floods stood up in a heap; the deeps congealed in the heart of the sea. 9 The enemy said, "I will pursue, I will overtake, I will divide the spoil, my desire shall have its fill of them. I will draw my sword; my hand shall destroy them." 10 You blew with your wind; the sea covered them; they sank like lead in the mighty waters.
"'11 Who is like you, O LORD, among the gods? Who is like you, majestic in holiness, awesome in glorious deeds, doing wonders? 12 You stretched out your right hand; the earth swallowed them.
"'13 You have led in your steadfast love the people whom you have redeemed; you have guided them by your strength to your holy abode. 14 The peoples have heard; they tremble; pangs have seized the inhabitants of Philistia. 15 Now are the chiefs of Edom dismayed; trembling seizes the leaders of Moab; all the inhabitants of Canaan have melted away. 16 Terror and dread fall upon them; because of the greatness of your arm, they are still as a stone, till your people, O LORD, pass by, till the people pass by whom you have purchased. 17 You will bring them in and plant them on your own mountain, the place, O LORD, which you have made for your abode, the sanctuary, O LORD, which your hands have established. 18 The LORD will reign forever and ever.'
"19 For when the horses of Pharaoh with his chariots and his horsemen went into the sea, the LORD brought back the waters of the sea upon them, but the people of Israel walked on dry ground in the midst of the sea. 20 Then Miriam the prophetess, the sister of Aaron, took a tambourine in her hand, and all the women went out after her with tambourines and dancing. 21 And Miriam sang to them:
"'Sing to the LORD, for he has triumphed gloriously; the horse and his rider he has thrown into the sea.'"
John 20:19-21: "19 On the evening of that day, the first day of the week, the doors being locked where the disciples were for fear of the Jews, Jesus came and stood among them and said to them, 'Peace be with you.' 20 When he had said this, he showed them his hands and his side. Then the disciples were glad when they saw the Lord. 21 Jesus said to them again, 'Peace be with you. As the Father has sent me, even so I am sending you.'"
Romans 6:9-11: "9 We know that Christ, being raised from the dead, will never die again; death no longer has dominion over him. 10 For the death he died he died to sin, once for all, but the life he lives he lives to God. 11 So you also must consider yourselves dead to sin and alive to God in Christ Jesus."

Come, you faithful, raise the strain
Of triumphant gladness!
God has brought His Israel
Into joy from sadness,
Loosed from Pharaoh's bitter yoke
Jacob's sons and daughters,
Led them with unmoistened foot
Through the Red Sea waters.
'Tis the spring of souls today:
Christ has burst His prison
And from three days' sleep in death
As a sun has risen;
All the winter of our sins,
Long and dark, is flying
From His light, to whom is giv'n
Laud and praise undying.
Now the queen of seasons, bright
With the day of splendor,
With the royal feast of feasts
Comes its joy to render;
Comes to gladden faithful hearts
Which with true affection
Welcome in unwearied strain
Jesus' resurrection!
For today among His own
Christ appeared, bestowing
His deep peace, which evermore
Passes human knowing.
Neither could the gates of death
Nor the tomb's dark portal
Nor the watchers nor the seal
Hold Him as a mortal.
Alleluia! Now we cry
To our King immortal,
Who, triumphant, burst the bars
Of the tomb's dark portal.
Come, you faithful, raise the strain
Of triumphant gladness!
God has brought His Israel
Into joy from sadness!

The first verse of the hymn summarizes the events recounted in the text from Exodus, and "raise the strain / Of triumphant gladness" seems to come from the singing mentioned in verse 1: "Then Moses and the people of Israel sang this song to the LORD, saying, 'I will sing to the LORD, for he has triumphed gloriously....'"
The text from Romans might appear in the second verse - particularly the line "Christ has burst His prison" - but I think it shows up more clearly in the last verse. The lines "Who, triumphant, burst the bars / Of the tomb's dark portal" give a better sense of the finality of Christ's victory over death from verse 9: "We know that Christ, being raised from the dead, will never die again; death no longer has dominion over him."
The text from John appears at the beginning of the fourth verse: "For today among His own / Christ appeared, bestowing / His deep peace." The relative clause describing that "deep peace" ("which evermore / Passes human knowing") comes from Philippians 4:7: "And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus."
