They agree with nothing regarding the remnant (they do not include the word), and Paul's definition and description stand.
Actually, the prophecies concerning this small group of survivors repeatedly use that very word:
21 The
remnant will return, the
remnant of Jacob, To the Mighty God. 22 For though your people, O Israel, be as the sand of the sea, A
remnant of them will return; The destruction decreed shall overflow with righteousness. 23 For the Lord GOD of hosts Will make a determined end In the midst of all the land.
Isaiah 10:21-23
1 There shall come forth a Rod from the stem of Jesse, And a Branch shall grow out of his roots. 2 The Spirit of the LORD shall rest upon Him, The Spirit of wisdom and understanding, The Spirit of counsel and might, The Spirit of knowledge and of the fear of the LORD. 3 His delight
is in the fear of the LORD, And He shall not judge by the sight of His eyes, Nor decide by the hearing of His ears; 4 But with righteousness He shall judge the poor, And decide with equity for the meek of the earth; He shall strike the earth with the rod of His mouth, And with the breath of His lips He shall slay the wicked. 5 Righteousness shall be the belt of His loins, And faithfulness the belt of His waist. 6 "The wolf also shall dwell with the lamb, The leopard shall lie down with the young goat, The calf and the young lion and the fatling together; And a little child shall lead them. 7 The cow and the bear shall graze; Their young ones shall lie down together; And the lion shall eat straw like the ox. 8 The nursing child shall play by the cobra's hole, And the weaned child shall put his hand in the viper's den. 9 They shall not hurt nor destroy in all My holy mountain, For the earth shall be full of the knowledge of the LORD As the waters cover the sea. 10 "And in that day there shall be a Root of Jesse, Who shall stand as a banner to the people; For the Gentiles shall seek Him, And His resting place shall be glorious." 11 It shall come to pass in that day
That the LORD shall set His hand again the second time To recover the
remnant of His people who are left, From Assyria and Egypt, From Pathros and Cush, From Elam and Shinar, From Hamath and the islands of the sea. 12 He will set up a banner for the nations, And will assemble the outcasts of Israel, And gather together the dispersed of Judah From the four corners of the earth. 13 Also the envy of Ephraim shall depart, And the adversaries of Judah shall be cut off; Ephraim shall not envy Judah, And Judah shall not harass Ephraim. 14 But they shall fly down upon the shoulder of the Philistines toward the west; Together they shall plunder the people of the East; They shall lay their hand on Edom and Moab; And the people of Ammon shall obey them. 15 The LORD will utterly destroy the tongue of the Sea of Egypt; With His mighty wind He will shake His fist over the River, And strike it in the seven streams, And make
men cross over dry-shod. 16 There will be a highway for the
remnant of His people Who will be left from Assyria, As it was for Israel In the day that he came up from the land of Egypt.
Isaiah 11:1-16
1 "Woe to the shepherds who destroy and scatter the sheep of My pasture!" says the LORD. 2 Therefore thus says the LORD God of Israel against the shepherds who feed My people: "You have scattered My flock, driven them away, and not attended to them. Behold, I will attend to you for the evil of your doings," says the LORD. 3 "But I will gather the
remnant of My flock out of all countries where I have driven them, and bring them back to their folds; and they shall be fruitful and increase. 4 I will set up shepherds over them who will feed them; and they shall fear no more, nor be dismayed, nor shall they be lacking," says the LORD.
Jeremiah 23:1-4
7 For thus says the LORD: "Sing with gladness for Jacob, And shout among the chief of the nations; Proclaim, give praise, and say, 'O LORD, save Your people, The
remnant of Israel!' 8 Behold, I will bring them from the north country, And gather them from the ends of the earth,
Among them the blind and the lame, The woman with child And the one who labors with child, together; A great throng shall return there. 9 They shall come with weeping, And with supplications I will lead them. I will cause them to walk by the rivers of waters, In a straight way in which they shall not stumble; For I am a Father to Israel, And Ephraim
is My firstborn.
Jeremiah 31:7-9
12 "I will surely assemble all of you, O Jacob, I will surely gather the
remnant of Israel; I will put them together like sheep of the fold, Like a flock in the midst of their pasture; They shall make a loud noise because of
so many people.
Micah 2:12
6 "In that day," says the LORD, "I will assemble the lame, I will gather the outcast And those whom I have afflicted; 7 I will make the lame a
remnant, And the outcast a strong nation; So the LORD will reign over them in Mount Zion From now on, even forever.
Micah 4:6-7
3 Therefore He shall give them up, Until the time
that she who is in labor has given birth; Then the
remnant of His brethren Shall return to the children of Israel. 4 And He shall stand and feed
His flock In the strength of the LORD, In the majesty of the name of the LORD His God; And they shall abide, For now He shall be great To the ends of the earth;
Micah 5:3-4
7 Then the
remnant of Jacob Shall be in the midst of many peoples, Like dew from the LORD, Like showers on the grass, That tarry for no man Nor wait for the sons of men. 8 And the
remnant of Jacob Shall be among the Gentiles, In the midst of many peoples, Like a lion among the beasts of the forest, Like a young lion among flocks of sheep, Who, if he passes through, Both treads down and tears in pieces, And none can deliver. 9 Your hand shall be lifted against your adversaries, And all your enemies shall be cut off.
Micah 5:7-9
8 Because you have plundered many nations, All the
remnant of the people shall plunder you, Because of men's blood And the violence of the land
and the city, And of all who dwell in it.
Habakkuk 2:8
7 The coast shall be for the
remnant of the house of Judah; They shall feed
their flocks there; In the houses of Ashkelon they shall lie down at evening. For the LORD their God will intervene for them, And return their captives. 8 "I have heard the reproach of Moab, And the insults of the people of Ammon, With which they have reproached My people, And made arrogant threats against their borders. 9 Therefore, as I live," Says the LORD of hosts, the God of Israel, "Surely Moab shall be like Sodom, And the people of Ammon like Gomorrah-- Overrun with weeds and saltpits, And a perpetual desolation. The residue of My people shall plunder them, And the
remnant of My people shall possess them."
Zephaniah 2:7-9
10 From beyond the rivers of Ethiopia My worshipers, The daughter of My dispersed ones, Shall bring My offering. 11 In that day you shall not be shamed for any of your deeds In which you transgress against Me; For then I will take away from your midst Those who rejoice in your pride, And you shall no longer be haughty In My holy mountain. 12 I will leave in your midst A meek and humble people, And they shall trust in the name of the LORD. 13 The
remnant of Israel shall do no unrighteousness And speak no lies, Nor shall a deceitful tongue be found in their mouth; For they shall feed
their flocks and lie down, And no one shall make
them afraid."
Zephaniah 3:10-13
11 'But now I
will not
treat the
remnant of this people as in the former days,' says the LORD of hosts. 12 'For the seed
shall be prosperous, The vine shall give its fruit, The ground shall give her increase, And the heavens shall give their dew-- I will cause the
remnant of this people To possess all these. 13 And it shall come to pass
That just as you were a curse among the nations, O house of Judah and house of Israel, So I will save you, and you shall be a blessing. Do not fear, Let your hands be strong.' 14 "For thus says the LORD of hosts: 'Just as I determined to punish you When your fathers provoked Me to wrath,' Says the LORD of hosts, 'And I would not relent, 15 So again in these days I am determined to do good To Jerusalem and to the house of Judah. Do not fear.
Zechariah 8:11-15
