Christians, can you please quote some Biblical pages where premarital (specifically) is condemned?

According to 1 Corinthians 7:2, “yes” is the clear answer, “But since there is so much immorality, each man should have his own wife, and each woman her own husband.” In this verse, Paul states that marriage is the “cure” for ual immorality. First Corinthians 7:2 is essentially saying because people cannot control themselves and so many people are having imm outside of marriage, people should get married, so they can fulfill their pions in a moral way.
