Was Jesus angry?

14 And the anger of the Lord was kindled against Moses, and he said, Is not Aaron the Levite thy brother? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart.

is this a figure of speech or was God really angry at Moses for being afraid?

God could have been angry with Moses because Moses had excuses why he could not do what God told him to do. Not believing that God would enable him.

Uzzah put forth his hand to the ark of God, and took hold of it; for the oxen shook it. And the anger of the Lord was kindled against Uzzah, and God smote him there for his error; and there he died by the ark of God." Uzzah was angry with the oxen, because they stumbled. He showed a manifest distrust of God, as though he who had brought the ark from the land of the Philistines, could not take care of it. Angels who attended the ark struck down Uzzah for presuming impatiently to put his hand upon the ark of God. {1SP 410.1}

Interesting that the angels killed Uzzah but God takes the responsibility maybe because the angels are under His command. Maybe the anger of the Lord can be a metaphor for the consequences of His error?
