Exodus 10:5

10:5 They will cover the surface of the earth, so that you will be unable to see the ground. They will eat the remainder of what escaped – what is left over for you – from the hail, and they will eat every tree that grows for you from the field.

Exodus 23:11

23:11 But in the seventh year you must let it lie fallow and leave it alone so that the poor of your people may eat, and what they leave any animal in the field may eat; you must do likewise with your vineyard and your olive grove.
