Exodus 20:5 warns of God visiting iniquity on children, explaining why the plague here strikes Jehoram's children and wives.

Leviticus 26:21 lists plague as a covenant curse for disobedience, providing the legal background for the judgment pronounced here.

Micah 6:16 condemns following the house of Ahab, the exact sin Jehoram committed, and warns of desolation — a parallel judgment.
