1 Peter 1:1-9: "1 Peter, an apostle of Jesus Christ,
"To those who are elect exiles of the dispersion in Pontus, Galatia, Cappadocia, Asia, and Bithynia, 2 according to the foreknowledge of God the Father, in the sanctification of the Spirit, for obedience to Jesus Christ and for sprinkling with his blood:
"May grace and peace be multiplied to you.
"3 Blessed be the God and Father of our Lord Jesus Christ! According to his great mercy, he has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead, 4 to an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you, 5 who by God's power are being guarded through faith for a salvation ready to be revealed in the last time. 6 In this you rejoice, though now for a little while, if necessary, you have been grieved by various trials, 7 so that the tested genuineness of your faith - more precious than gold that perishes though it is tested by fire - may be found to result in praise and glory and honor at the revelation of Jesus Christ. 8 Though you have not seen him, you love him. Though you do not now see him, you believe in him and rejoice with joy that is inexpressible and filled with glory, 9 obtaining the outcome of your faith, the salvation of your souls."
Matthew 28:19: "'Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit'"
Romans 6:4: "We were buried therefore with him by baptism into death, in order that, just as Christ was raised from the dead by the glory of the Father, we too might walk in newness of life."
John 6:39: "'And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day.'"

I bind unto myself today
The strong name of the Trinity
By invocation of the same,
The Three in One and One in Three.
I bind this day to me forever,
By pow'r of faith, Christ's incarnation,
His Baptism in the Jordan River,
His cross of death for my salvation,
His bursting from the spiced tomb,
His riding up the heav'nly way,
His coming at the day of doom,
I bind unto myself today.
I bind unto myself today
The pow'r of God to hold and lead,
His eye to watch, His might to stay,
His ear to hearken to my need,
The wisdom of my God to teach,
His hand to guide, His shield to ward,
The Word of God to give me speech,
His heav'nly host to be my guard.
Against the demon snares of sin,
The vice that gives temptation force,
The natural lusts that war within,
The hostile foes that mar my course;
Or few or many, far or nigh,
In ev'ry place and in all hours,
Against their fierce hostility,
I bind to me those holy pow'rs.
I bind unto myself the name,
The strong name of the Trinity
By invocation of the same,
The Three in One and One in Three,
Of whom all nature has creation,
Eternal Father, Spirit, Word.
Praise to the Lord of my salvation;
Salvation is of Christ the Lord!

Matthew 28:19 appears in both the first and last verses ("the strong name of the Trinity"). The other passages aren't so easy to identify. Part of the passage from 1 Peter 1 and Romans 6:4 could be cited for the second verse ("His cross of death for my salvation, / His bursting from the spiced tomb"), and 1 Peter 1 and John 6:39 could be cited for the last line ("Salvation is of Christ the Lord!"), but there's not a strong resemblance between any of these.
Incidentally, the phrases "few or many, far or nigh" are merisms.
