'Sell' in the Bible

I said to them, "We, after our ability, have redeemed our brothers the Jews that were sold to the nations; and would you even sell your brothers, and should they be sold to us?" Then they held their peace, and found never a word.

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.
