'Tongue' in the Bible

And Moses said to the Lord, O Lord, I am not a man of words; I have never been so, and am not now, even after what you have said to your servant: for talking is hard for me, and I am slow of tongue.

But against the children of Israel, man or beast, not so much as the tongue of a dog will be moved: so that you may see how the Lord makes a division between Israel and the Egyptians.
