'Tremble' in the Bible

You must not tremble in their presence, for the Lord your God, who is present among you, is a great and awesome God.

"Listen, Israel! Today you are moving forward to do battle with your enemies. Do not be fainthearted. Do not fear and tremble or be terrified because of them,

Be strong and courageous! Do not fear or tremble before them, for the Lord your God is the one who is going with you. He will not fail you or abandon you!"
