Albert Barnes Commentary Nehemiah 10:31

"and if the peoples of the land bring wares or any grain on the sabbath day to sell, that we would not buy of them on the sabbath, or on a holy day; and that we would forego the seventh year, and the exaction of every debt." — Nehemiah 10:31 (ASV)

Bring ware ... on the sabbath day – Compare (Nehemiah 13:16), where this desecration of the Sabbath is shown to have commonly taken place.

Leave the seventh year ... – That is, “let the land rest in the sabbatical year” (margin reference) and give up the “pledge-taking” (Nehemiah 10:2–10).
