Nehemiah 5:8; Nehemiah 5:16

8 I said to them, "We according to our ability have redeemed our Jewish brothers who were sold to the nations; now would you even sell your brothers that they may be sold to us?" Then they were silent and could not find a word to say.
16 I also applied myself to the work on this wall; we did not buy any land, and all my servants were gathered there for the work.
