And there was a famine in the land: and Abram went down into Egypt to sojourn there; for the famine was severe in the land.
Read Chapter 12
Didymus the Blind
The content on the literal level is clear. As for the spiritual meaning, it is this. Those who are wise in God are above the earth, since they are not of the earth. A famine then came over the earth, because for those who are concerned about earthly things, there often occurs a famine in this sense, that they no longer hear the word of the Lord. Then, if they are worthy of it, the Word is given back to them one day. Thus Abraham went to Egypt to “sojourn” there, not to dwell there, because he had sympathy for the victims of the famine. Likewise Daniel and his companions did not come to Babylon because of sins they had committed but to aid the people who had been deported there on account of their own sins.
