# When I cut off your staff of food

"When I stop you from being able to get food" or "When I make it impossible for you to get the food you depend on"

# ten women will be able to bake your bread in one oven

This implies that there will be so little flour that one small oven will be able to hold all the bread that many women can put into it.

# they will distribute your bread by weight

This means there will be so little food that they will have to measure how much each person gets.
