5:22And Moses returned unto the LORD, and said, Lord, wherefore hast thou so evil entreated this people? why is it that thou hast sent me?

5:23For since I came to Pharaoh to speak in thy name, he hath done evil to this people; neither hast thou delivered thy people at all.

6:12And Moses spake before the LORD, saying, Behold, the children of Israel have not hearkened unto me; how then shall Pharaoh hear me, who am of uncircumcised lips?

32:19And it came to pass, as soon as he came nigh unto the camp, that he saw the calf, and the dancing: and Moses' anger waxed hot, and he cast the tables out of his hands, and brake them beneath the mount.
