This is the plaque given by Nardus & Sipora Groen to Lubertus & Geeske te Kiefte at the end of World War II in gratitude for their remarkable and selfless sacrifice.
It is from Psalm 31, Verse 9 and translates as follows:
“You will not abandon me into enemy hands,
but will set my feet in a free and open space.”
