Sarah's Paradox

Sarah hated Hagar and sent her away both when she was pregnant with Yishmael and when Yishmael laughed/played at Yitzchok's weaning - Yitzchok being Sarah's son.

But the gematria (mathematical value of the letters) of Hagar is 208 - and the gematria of Yitzchok is . . . also 208.

So what she hated and rejected in Hagar came to her as Yitzchok and she loved him - but he was taken away from her as well through the Akedah - or so she thought - and she died.

Perhaps had she loved and embraced Hagar, she would not have lost Yitzchok.
