The Jews were commanded by God: “In case you build a new house, you must also make a parapet for your roof, that you may not place bloodguilt upon your house because someone... might fall from it. ”
Dievs senajiem izraēliešiem bija pavēlējis: ” Kad tu sev uzcērti jaunu namu, tad darini arī margas savam lēzenam jumtam, ka tu neuzkrauji kādu asins vainu pār savu namu, ja kāds no tā nokristu. ” ( 5. Mozus 22: 8.)
