What was the difference for the Israelites between living in Egypt with a consistent source of water and living in the promised land where they would have to depend on rainfall?

The wet winter season in Israel runs from October to April, and 82% of Israel’s rain falls from December to February, with the northern part receives most of the rainfall. Therefore, the winter is when the ground is filled with water, which is also ideal for cultivating grains. Summer month is the harvest month as the Mediterranean Sea breeze will help them separate the grain kernel from the chaff.
