7:137 Jews Inheriting Egypt
The demand 20:47 was that let the bani israel leave and go to their lands safely. You could say that the true request was for safety (you can disagree with this). So then when pharoah was drowned they were safe and didn’t have to go. As for 7:134-137 I just said read from earlier on to show the cohesive narrative. It seems to show that the Egyptians were oppressing the Israelites so they were made to inherit the lands after them. Inherit would be used if someone dies and gives it to someone else or someone else takes it or is given it
Inheritance was with reference to land of Palestine as I see it becasue of the words مَشَٰرِقَ ٱلۡأَرۡضِ وَمَغَٰرِبَهَا ٱلَّتِى بَٰرَكۡنَا فِيهَاۖ .
