John Gill Commentary Exodus 6:4

"And I have also established my covenant with them, to give them the land of Canaan, the land of their sojournings, wherein they sojourned." — Exodus 6:4 (ASV)

And I have also established my covenant with them
With Abraham, Isaac, and Jacob, and with their posterity, so that it is sure and firm, and shall never be made null and void: to give them the land of Canaan ;
or to their children, which were as themselves: the land of their pilgrimage, wherein they were strangers ;
not being in actual possession of any part of it, but lived as pilgrims and strangers in it, as their posterity now did in another land not theirs; see (Hebrews 11:9Hebrews 11:13) .
