Avraham escaped the famine by temporarily moving to Egypt. According to the Ramban, Avraham should have trusted in God and stayed in the land in which he was told to live. But Ralbag writes that the story of the drought – and Avraham’s response – is an example of the proactive effort required in securing a proper livelihood.
This debate between the Ramban and the Ralbag raises a number of interesting questions, including whether their differing views relate to the unique circumstances faced by Avraham, or if they perhaps reflect broader perspectives on the proper balance between human effort and trust in God.
