The Sovereign Lord has given me a well-instructed tongue, to know the word that sustains the weary. He wakens me morning by morning, wakens my ear to listen like one being instructed. Isaiah 50:4
Because the Sovereign Lord helps me, I will not be disgraced. Therefore have I set my face like flint, and I know I will not be put to shame. Isaiah 50:7
But when I speak to you, I will open your mouth and you shall say to them, ‘This is what the Sovereign Lord says.’ Whoever will listen let them listen, and whoever will refuse let them refuse; for they are a rebellious people. Ezekiel 3:27
Do not be afraid of them, for I am with you and will rescue you,” declares the Lord.
Then the Lord reached out his hand and touched my mouth and said to me, “I have put my words in your mouth. See, today I appoint you over nations and kingdoms to uproot and tear down, to destroy and overthrow, to build and to plant.” Jeremiah 1:8-10
As the rain and the snow come down from heaven, and do not return to it without watering the earth and making it bud and flourish, so that it yields seed for the sower and bread for the eater, so is my word that goes out from my mouth:
It will not return to me empty, but will accomplish what I desire and achieve the purpose for which I sent it. Isaiah 55:10-11
