Sweden: Professor links "disproportionate attacks" to Biblical precepts

Swedish professor Sven-Eric Liedman tweeted as follows:

"Ja, sjufalt hämnad bliver Kain, men Lemek sju- och sjuttiofalt." - Så står det i Gamla testamentet, och statet Israel lever efter detta

"If Cain shall be avenged sevenfold, truly Lamech seventy and sevenfold." - so it says in the Old Testament and the State of Israel lives by this.
