So they went up out of Egypt and came to the land of Canaan to their father Jacob.
We have here the good news brought to Jacob. 1. The relation of it, at first, sunk his spirits. When, without any preamble, his sons came in, crying, Joseph is yet alive, each striving which should first proclaim it, perhaps he thought they bantered him, and the affront grieved him; or the very mention of Joseph's name revived his sorrow, so that his heart fainted, Gen 45:26.
Commenting on Genesis 45:25-28
And they went up out of Egypt,.... That lying lower than the land of Canaan: and came into the land of Canaan unto Jacob their father; they found him alive and well.
Gen 45:25-28 When they got back, and brought word to their father, “Joseph is still living, yea (וכי an emphatic assurance, Ewald, §3306) he is ruler in all the land of Egypt, his heart stopped, for he believed them not;” i.e., his heart did not beat at this joyful news, for he put no faith in what they said.
