'Spoken' in the Bible

"And Yahweh heard the sound of your words {when you spoke to me}, and Yahweh said to me, 'I have heard the sound of the words of this people that they have spoken to you; [they] are right [with respect to] all that they have spoken.

And if you say {to yourself}, 'How can we know the word that Yahweh has not spoken to him?'

[Whenever] what the prophet spoke in the name of Yahweh, the thing does not take place and [does] not come [about], that [is] the thing that Yahweh has not spoken to him. Presumptuously the prophet spoke it; you shall not fear that prophet."
