'Speakest' in the Bible

and now, go, and I -- I am with thy mouth, and have directed thee that which thou speakest;'

'Be mindful of Abraham, of Isaac, and of Israel, Thy servants, to whom Thou hast sworn by Thyself, and unto whom Thou speakest: I multiply your seed as stars of the heavens, and all this land, as I have said, I give to your seed, and they have inherited to the age;'
