1812, Emanuel Swedenborg [aut.] and J. Clowes [tr.], Arcana Cœlestia VII (2nd ed.), chapter xli, pages 210⁽¹⁾ and 270⁽²⁾ ⁽¹⁾ Let Pharaoh…quintate^✸ the land of Egypt in the seven years of abundance of provision. ✸ Quintate signifies to take a fifth of any thing, and is derived from the Latin quintus, signifying a fifth, as decimate is derived from decimus, signifying a tenth. ⁽²⁾ “And let him quintate the land” — that hereby is signified which were to be preserved and afterwards stored up, appears from the signification of quintating, as here involving the like with decimating.
