सरुको हरफ - जर्मन - ... mit dem Engel reden

These are the first two verses from an uncollected (and not well known) poem by Rainer Maria Rilke, written in 25.9.1914.
I know the whole poem by heart, and understand well its meaning (even I've translated it into my own mother tongue); but I'd love to read these two verses in Latin, and in classical Greek.
A fancy, perhaps; but quite an urge as well...
