No recorded blessing

I used to think that 2 Nephi 4 was the blessing of Nephi by Lehi but I realize that it isn’t. We have no recorded blessing and counsel from Lehi to Nephi. Similarly, but certainly for far different reasons, we have no recorded blessings for Lamannan and Lemuel. What we do have is clearings for their children to shield them from the consequences if their unrighteousness and answer it at its source
