John Gill Commentary Leviticus 25:3

"Six years thou shalt sow thy field, and six years thou shalt prune thy vineyard, and gather in the fruits thereof;" — Leviticus 25:3 (ASV)

Six years you shall sow your field
Under which is comprehended everything relating to agriculture, both before and after sowing, as dunging the land, ploughing and harrowing it, treading the corn, reaping and gathering it in; see (Exodus 23:10);

and six years you shall prune your vineyard, and gather in the fruit
of it;
which is not to be restrained to vineyards only, but to be extended to oliveyards, orchards and gardens, and to the planting and cultivating of them, and gathering in the fruits of them.
