Parshat Chayei Sarah
Eliezer
Eliezer prayed by the water because it is good to pray near
water since prayer is compared to water.[2]
Keturah
When Hagar did Teshuva for returning to idolatry, then Avrohom
took her back in peace and remarried her.[1]
Rivka
Unlike Adom who was banished from the Upper Realms due to his
wife, Yitzchak was raised to greater levels by marrying Rivka,
since she was a replacement for Sarah.[3]
