OFFICER: You here shall swear upon this sword of justice,
That you, Cleomenes and Dion, have
Been both at Delphos, and from thence have brought
The seal'd-up oracle, by the hand deliver'd
Of great Apollo's priest; and that, since then,
You have not dared to break the holy seal
Nor read the secrets in't.
CLEOMENES/DION: All this we swear.
LEONTES: Break up the seals and read.
