Leviticus 25:20-22

Amplified Bible

²⁰ And if you say, “What are we going to eat in the seventh year if we do not sow [seed] or gather in our crops?” ²¹ then [this is My answer:] I will order My [special] blessing for you in the sixth year, so that it will produce [sufficient] crops for three years. ²² When you are sowing the eighth year, you can still eat old things from the crops, eating the old until the ninth year when its crop comes in.
