'Word' in the Bible

Please, remember the word that you have commanded to your servant Moses, saying, 'If you act unfaithfully I will scatter you all among the nations.

and I said to them: "We ourselves have bought back our brothers the Jews who were sold to the nations as we were able. But now you yourselves have sold your brothers so they may be sold to us!" They were silent and could not find a word [to say].

And Sanballat sent his servant with an open letter, [another] word like this to me a fifth time, in his hand.

You found his heart faithful before you and made a covenant with him to give the land of the Canaanite, the Hittite, the Amorite, the Perizzite, the Jebusite and the Girgashite--to give [it] to his seed. And you have kept your word because you are righteous.
