Genesis 41:36

And that food shall be for store to the land against the seven years of famine, which shall be in the land of Egypt; that the land perish not through the famine.

Cross-references

In Genesis 41:30, the seven-year famine is foretold — Joseph's storage plan here directly addresses that coming crisis.

In Genesis 47:13-25, the stored food is used to sustain Egypt — exactly the reserve described in 41:36.
