'Famine in the Land' in the Bible

And there is a famine in the land, and Abram goeth down towards Egypt to sojourn there, for the famine is grievous in the land;

And there is a famine in the land, besides the first famine which was in the days of Abraham, and Isaac goeth unto Abimelech king of the Philistines, to Gerar.

and they say unto Pharaoh, 'To sojourn in the land we have come, for there is no pasture for the flock which thy servants have, for grievous is the famine in the land of Canaan; and now, let thy servants, we pray thee, dwell in the land of Goshen.'
