These people were pre-destined to be troublemakers.
For those who remember the story of Abraham's mistress "Hagar" from Genesis 16 (NIV):
10 The angel added, "I will so increase your descendants that they will be too numerous to count."
11 The angel of the LORD also said to her:
"You are now with child
and you will have a son.
You shall name him Ishmael, [a]
for the LORD has heard of your misery.
12 He will be a wild donkey of a man;
his hand will be against everyone
and everyone's hand against him,
and he will live in hostility
toward all his brothers."
