Question: Who are 'they' in this text?:
18 But I say, Did

30 What shall we say then? That the Gentiles, who followed not after righteousness, attained to righteousness, even the righteousness which is of faith:
31 but
 Israel, following after a law of righteousness, did not arrive at 
that law.
32 Wherefore? Because 
they sought it not by faith, but as it were by works. 
They stumbled at the stone of stumbling;
33 even as it is written, Behold, I lay in 
Zion a stone of stumbling and a rock of offence: And he that believeth on him shall not be put to shame.
1 Brethren, my heart`s desire and my supplication to God is for 
them, that
 they may be saved.
2 For I bear
 them witness that 
they have a zeal for God, but not according to knowledge.
3 For being ignorant of God`s righteousness, and seeking to establish their own, 
they did not subject themselves to the righteousness of God.
4 For Christ is the end of the law unto righteousness to every one that believeth.
5 For Moses writeth that the man that doeth the righteousness which is of the law shall live thereby.
6 But the righteousness which is of faith saith thus, Say not in thy heart, Who shall ascend into heaven? (that is, to bring Christ down
7 or, Who shall descend into the abyss? (That is, to bring Christ up from the dead.)
8 But what saith it? The word is nigh thee, in thy mouth, and in thy heart: that is, the word of faith, which we preach:
9 because if thou shalt confess with thy mouth Jesus 
as Lord, and shalt believe in thy heart that God raised him from the dead, thou shalt be saved:
10 for with the heart man believeth unto righteousness; and with the mouth confession is made unto salvation.
11 For the scripture saith, Whosoever believeth on him shall not be put to shame.
12 For there is no distinction between Jew and Greek: for the same 
Lord is Lord of all, and is rich unto all that call upon him:
13 for, Whosoever shall call upon the name of the Lord shall be saved.
14 How then shall 
they call on him in whom
 they have not believed? and how shall 
they believe in him whom 
they have not heard? and how shall 
they hear without a preacher?
15 and how shall they preach, except they be sent? even as it is written, How beautiful are the feet of them that bring glad tidings of good things!
16 But
 they did not all hearken to the glad tidings. For Isaiah saith, Lord, who hath believed our report?
17 So belief 
cometh of hearing, and hearing by the word of Christ.
18 But I say, Did 
they not hear? Yea, verily, Their sound went out into all the earth, And their words unto the ends of the world.
