Exodus 6:12; 1 Samuel 18:18; Isaiah 6:5; Isaiah 6:8; Jeremiah 1:6

12 But Moses said to the Lord, Behold, the people of Israel have tnot listened to me. How then shall Pharaoh listen to me, for uI am of uncircumcised lips?


18 And David said to Saul, zWho am I, and who are my relatives, my father's clan in Israel, that I should be son-in-law to the king?


And I said: Woe is me! yFor I am lost; zfor I am a man of unclean lips, and I dwell in the midst of a people of unclean lips; for my eyes have seen the aKing, the Lord of hosts!


Isaiah's Commission from the Lord

And I heard the voice of the Lord saying, Whom shall I send, and who will go for cus? Then I said, Here I am! Send me.


Then I said, Ah, Lord God! Behold, lI do not know how to speak, mfor I am only a youth.
