'Brother' in the Bible

“Because of the violence you did against your brother Jacob,Shame shall cover you [completely],And you shall be cut off forever.

“On the day that [Jerusalem was destroyed] you stood aloof [from your brother Jacob]—On the day that strangers took his forces captive and carried off his wealth,And foreigners entered his gatesAnd cast lots for Jerusalem [dividing the city for plunder]—You too were like one of them [collaborating with the enemy].
