Chastity is the seal of grace. [ Lady Huntington ]

Simplicity is the seal of truth. [ Boerhaave ]

A combination, and a form, indeed
Where every god did seem to set his seal
To give the world assurance of a man. [ William Shakespeare, Hamlet ]

Upon thy cheek lay I this zealous kiss, as seal to the indenture of my love. [ William Shakespeare ]

The seal of suffering impressed upon our destiny announces in clear characters our high calling. [ De Gerando ]

Envy sets the stronger seal on desert; if he have no enemies, I should esteem his fortune most wretched. [ Ben Jonson ]

Candor is the seal of a noble mind, the ornament, and pride of man, the sweetest charm of woman, the scorn of rascals and the rarest virtue of sociability. [ Bentzel-Sternaft ]

Put a seal upon your lips and forget what you have done. After you have been kind, after love hath stolen forth into the world and done its beautiful work, go back into the shade again and say nothing about it.

Over Under. These words have various meanings besides the designation of mere locality, and are often misapplied. The terms under oath, under hand and seal, under arms, under his own signature, etc., are fully established and authorized forms of expression, which do not concern the relative positions of the persons and things indicated, but are idiomatic. Hence, over his own signature, is an unjustifiable phrase, despite the fact that the signature is really at the bottom of the instrument signed. [ Pure English, Hackett And Girvin, 1884 ]
