The whole section of what is now named "Romans" has this clear predestination doctrine. The potter passage in context:
11 for though the twins were not yet born and had not done anything good or bad, so that ( Z ) God's purpose according to His choice would stand, not because of works but because of Him who calls,
12 it was said to her, " ( AA ) THE OLDER WILL SERVE THE YOUNGER."
13 Just as it is written, " ( AB ) JACOB I LOVED, BUT ESAU I HATED."
14 ( AC ) What shall we say then? ( AD ) There is no injustice with God, is there? ( AE ) May it never be!
15 For He says to Moses, " ( AF ) I WILL HAVE MERCY ON WHOM I HAVE MERCY, AND I WILL HAVE COMPASSION ON WHOM I HAVE COMPASSION."
16 So then it does not depend on the man who wills or the man who ( AG ) runs, but on ( AH ) God who has mercy.
17 For the Scripture says to Pharaoh, " ( AI ) FOR THIS VERY PURPOSE I RAISED YOU UP, TO DEMONSTRATE MY POWER IN YOU, AND THAT MY NAME MIGHT BE PROCLAIMED THROUGHOUT THE WHOLE EARTH."
18 So then He has mercy on whom He desires, and He ( AJ ) hardens whom He desires.
19 ( AK ) You will say to me then, " ( AL ) Why does He still find fault? For ( AM ) who resists His will?"
20 On the contrary, who are you, ( AN ) O man, who ( AO ) answers back to God? ( AP ) The thing molded will not say to the molder, "Why did you make me like this," will it?
21 Or does not the potter have a right over the clay, to make from the same lump one vessel for honorable use and another for common use?
22 What if God, although willing to demonstrate His wrath and to make His power known, endured with much ( AQ ) patience vessels of wrath ( AR ) prepared for destruction?
23 And He did so to make known ( AS ) the riches of His glory upon ( AT ) vessels of mercy, which He ( AU ) prepared beforehand for glory,
24 even us, whom He also ( AV ) called, ( AW ) not from among Jews only, but also from among Gentiles.
chapter 8:
28 And we know that [ c ] God causes ( BG ) all things to work together for good to those who love God, to those who are ( BH ) called according to His purpose.
29 For those whom He ( BI ) foreknew, He also ( BJ ) predestined to become ( BK ) conformed to the image of His Son, so that He would be the ( BL ) firstborn among many brethren;
30 and these whom He ( BM ) predestined, He also ( BN ) called; and these whom He called, He also ( BO ) justified; and these whom He justified, He also ( BP ) glorified.
These sections of Romans were originally addressed to the Ephesian congregation as part of a second letter (discussed before). Interestingly Ephesians 1 opens with this same doctrine:
4 just as ( K ) He chose us in Him before ( L ) the foundation of the world, that we would be ( M ) holy and blameless before [ b ] Him ( N ) In love
5 He ( O ) predestined us to ( P ) adoption as sons through Jesus Christ to Himself, ( Q ) according to the kind intention of His will,
The writer (ostensibly Paul) definitely endorsed the doctrine of predestination on an individual level. Strangely this doctrine is less pronounced in the rest of the body of Pauline writings.
