Ha'azinu: Chapter 55
"Can a woman forget her sucking child"

Rabbi Chiya has received a spirit message about the title verse that he does not understand, and so he is going to see Rabbi Shimon for an interpretation. Rabbi Yitzchak remembers that Rabbi Elazar explained in the name of his father that Yisrael are God's children and so they cannot possibly be forgotten. God can no more forget His children than He can forget His own Name, because they are attached to His Name.
