Simeon and Levi are brethren; instruments of cruelty are in their habitations.
Simeon and Levi are brethren - i:e., united by similar dispositions as by blood relationship.
Instruments of cruelty are in their habitations. The meaning of this last word х mªkeeroteeyhem (H4380)] has been much disputed. Without enumerating the various significations which have been attached to it by different writers, according as they derived it from one or another root, the samplest and most direct appears to be that suggested by Gesenius, who, tracing it to kowr (H1060), or kaaraah (H3738), to pierce, renders the clause, 'instruments of violence are their swords.' The Septuagint has, 'they executed in concert their iniquitous plot of destruction.'
