For translations that use prose here, a paragraph break is appropriate, as in Good News Bible.

They tilled their land in peace: Good News Bible specifies the referent for the pronoun They by saying “The Jews,” which is helpful.

The ground gave its increase may be rendered “The land produced crops [or, grain].”

And the trees of the plains their fruit: Fruit trees also produced crops. Compare Lev 26.4.

An alternative model for this verse is:

• The Jews farmed their land in peace. The land produced crops [or, grain], and the trees produced fruit.
