"So Abram said to Lot: 'Please let there be no more strife between me and you, and between my herdsmen and your herdsmen, for we are kinsmen'"
Parashat Lech Lecha, 13:8
"We shall continue to love the people of Israel, and we shall continue to fight for the people of Israel...Help me to persuade my people that it is forbidden for brother to raise a hand against brother, that it is forbidden that a Hebrew weapon be used against Hebrew fighters."
Menachem Begin, in the 'Speech of Tears' after the brutal attack on the Altalena by his 'brothers'.
