'Speech' in the Bible

And when they went, I heard the noise of their wings, like the noise of great waters, as the voice of the Almighty, the voice of speech, as the noise of an host: when they stood, they let down their wings.

For thou art not sent to a people of a strange speech and of an hard language, but to the house of Israel;

Not to many people of a strange speech and of an hard language, whose words thou canst not understand. Surely, had I sent thee to them, they would have hearkened unto thee.

Then I said, "O sovereign Lord! They are saying of me, 'Does he not simply speak in eloquent figures of speech?'"

You exalted yourselves against me with your speech and hurled many insults against me -- I have heard them all!
