Vous avez cherché: the iron never lies (Anglais - Latin)

strike while the iron is hot.

he shall flee from the iron weapon, and the bow of steel shall strike him through.
fugiet arma ferrea et inruet in arcum aereu

dixit autem homo dei ubi cecidit at ille monstravit ei locum praecidit ergo lignum et misit illuc natavitque ferru

forasmuch as thou sawest that the stone was cut out of the mountain without hands, and that it brake in pieces the iron, the brass, the clay, the silver, and the gold; the great god hath made known to the king what shall come to pass hereafter: and the dream is certain, and the interpretation thereof sure.
secundum quod vidisti quod de monte abscisus est lapis sine manibus et comminuit testam et ferrum et aes et argentum et aurum deus magnus ostendit regi quae futura sunt postea et verum est somnium et fidelis interpretatio eiu
