Verse 2. - And he said, Behold, I have heard (this does not imply that the rumor had not also reached Jacob's sons, but only that the proposal to visit Egypt did not originate with them) that there is corn - שֶׁבֶר ut supra, σῖτος ( LXX.), triticum (Vulgate) - in Egypt: get you down thither. That Jacob did not, like Abraham (Genesis 12:10)and Isaac (Genesis 26:2), propose to remove his family to Egypt, may be explained either by the length of the journey, which was too great for so large a household, or by the circumstance that the famine prevailed in Egypt as well as Canaan (Gerlach). That he entrusted his sons, and not his servants, with the mission, though perhaps dictated by a sense of its importance (Lawson), was clearly of Divine arrangement for the further accomplishment of the Divine plan concerning Joseph and his brethren. And buy (i.e. buy corn, the verb being a denominative from שֶׁבֶר, corn) for us from thence. From this it is apparent that the hitherto abundant flocks and herds of the patriarchal family had been greatly reduced by the long-continued and severe drought, thus requiring them to obtain food from Egypt, if either any portion of their flocks were to be saved, or themselves to escape starvation, as the patriarch explained to his sons. That we may (literally, and we shall) live, and not die.

42:1-6 Jacob saw the corn his neighbours had bought in Egypt, and brought home. It is a spur to exertion to see others supplied. Shall others get food for their souls, and shall we starve while it is to be had? Having discovered where help is to be had, we should apply for it without delay, without shrinking from labour, or grudging expense, especially as regards our never-dying souls. There is provision in Christ; but we must come to him, and seek it from him.And he said, behold, I have heard that there is corn in Egypt,.... This explains what is meant by the phrase he saw, one sense being put for another:

get ye down thither; as fast as you can without delay; Egypt lay lower than Canaan, and therefore they are bid to go down, as when they went from thence to Canaan they are said to go up, Genesis 45:25,

and buy for us from thence, that we may live, and not die; which shows the famine was very pressing, since, unless they could buy corn from Egypt they could not live, but must die.
