Genesis 43:2
And it came to pass, when they had eaten up the corn which they had brought out of Egypt, their father said unto them, Go again, buy us a little food.
Cross-reference
In Genesis 43:4, Judah insists Benjamin must go to buy food — directly continuing the dilemma introduced in verse 2 about needing more grain.
In Genesis 42:1, Jacob first tells his sons to go buy grain — the same command repeated here as the famine persists.
In Genesis 42:2, Jacob sends his sons to Egypt for grain — the same errand is repeated here, but now with urgency as the famine continues.
Genesis 44:1 continues the story: Joseph's command to fill sacks and hide the cup follows directly from the brothers' return trip initiated in 43:2.
In Genesis 44:25, the brothers quote their father's command from 43:2, explaining to the steward why they returned.
Acts 7:12 explicitly recounts Jacob sending his sons to Egypt for grain, referencing the same famine context as Genesis 43:2.
