Charles Spurgeon Commentary Leviticus 25:4-5

"but in the seventh year shall be a sabbath of solemn rest for the land, a sabbath unto Jehovah: thou shalt neither sow thy field, nor prune thy vineyard. That which groweth of itself of thy harvest thou shalt not reap, and the grapes of thy undressed vine thou shalt not gather: it shall be a year of solemn rest for the land." — Leviticus 25:4-5 (ASV)

You shall neither sow your field, nor prune your vineyard. That which grows of its own accord of your harvest you shall not reap, neither gather the grapes of your vine undressed: for it is a year of rest to the land.

A restful period in a restful land; all land to have rest, and yet to have fruitfulness in that rest; the rest of a garden, not the rest of a task. Thus it is oftentimes with God's people: when they rest most, they work best; and while they are resting, they are bearing fruit to God.
