Then Judah went up to him and said, “Oh, my lord, please let your servant speak a word in my lord's ears, and let not your anger burn against your servant, for you are like Pharaoh himself.
Genesis 44:18

Although Joseph had authority and power over many, he always operated under the authority of another, whether it was Jacob, God, or Pharaoh. One who is authorized to speak in the name of another, speaks *as* the other.

Remember what #yeshua (aka #jesus) said about whose words he spoke? Like Joseph, he operated under authority, speaking and doing only what the Father instructed him.
