לנוכח אשתו. בגימטריא אש וקש רמז שתלד יעקב שנא' בו והיה בית יעקב אש ועשו שנא' בו ובית עשו לקש: לנח אשתו, “in the presence of his wife.” The numerical value of the word אשתו=707, is the same as the combined numerical value of the words: אש וקש, “fire and straw.” This is a hint that Rivkah would give birth to one son, comparable in spiritual values to fire, and another whose value in terms of spiritual values was no better than straw. The prophet therefore compared Yaakov to fire and Esau to straw. (Ovadiah 18)
