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, 20:4 for the Lord your God goes with you to fight on your behalf against your enemies to give you victory.”

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!”
