More about Bechukotai

I have three questions about Leviticus 26:42:

1. Why are the names of the forefathers presented in reverse order in Leviticus 26:42?
2. Why is Jacob's name spelled with an vav?
3. And why does it say HaShem will remember his covenant with Abraham and Jacob, but regarding Isaac, the Hebrew does not use the word  "remember."

This teaching demonstrates how the land of Israel is an important part of the final redemption and the coming of the kingdom. The blessings in Bechukotai are prophetic descriptions of the land of Israel in the Messianic Era.
