Now Jacob saw that there was corn in Egypt, and Jacob said unto his sons: ‘Why do ye look one upon another?’
Zohar
Jacob wanted to prophesy concerning the exiles of his children in the land of Canaan and in any land wherein they dwelt which came from the land of Egypt; to wit, all exiles are included within Egypt. His heart broke, as it is written, "Now Jacob saw that there was corn (also: 'breaking') in Egypt" (Beresheet 42:1).
