Leviticus 25:11

A jubile shall that fiftieth year be unto you: ye shall not sow, neither reap that which groweth of itself in it, nor gather the grapes in it of thy vine undressed.

Cross-references

Leviticus 25:5-7 gives the same 'do not sow/reap' command for the Sabbath year—extending the Jubilee rule to the earlier cycle.

In Leviticus 27:17, the Jubilee year determines land value—connecting the farming restrictions here to how dedicated property is assessed.

Exodus 23:11 also commands letting the land lie fallow every seventh year—mirroring the Jubilee's agricultural rest here.
