2 Samuel 17:19

Kinuha ng asawa ng lalaki ang pantakip ng balon at inilatag ito sa bukana ng balon at hinagisan ito ng trigo, kaya walang isa ang nakakaalam na nasa balon sina Jonatan at Ahimaaz.

And the woman took and spread a covering over the well’s mouth, and spread ground corn thereon; and the thing was not known.
