For “If the righteous are repaid on earth, how much more the wicked and the sinner!” see 1 Peter 4:18.
Note that this quote in the New Testament is not taken from the Hebrew Bible but from the Greek Septuagint (LXX) which translates into English as “If the righteous is scarcely saved, where will the impious and the sinner appear.” (Translation by NETS — for the Greek version see the title’s tooltip)
