News of Rebecca's Birth Reaches Abraham on the Mountain

Yalkut Shimoni on Torah 102:3

"And it came to pass after these things that it was told to Abraham, saying, Behold, Milcah also has borne children" (Genesis 22:20). It is written, "A sound heart is the life of the flesh" (Proverbs 14:30). For while he was still on Mount Moriah, he received the good news that his son's mate had been born, as it is said, "And Bethuel begot Rebecca."
