Deuteronomy 20:4

‘Yahweh your God, who goes before you, will Himself fight on your behalf, just as He did for you in Egypt before your eyes,

‘Do not fear them, for Yahweh your God is the one fighting for you.’

“Be strong and courageous. Do not be afraid or be in dread of them, for Yahweh your God is the one who goes with you. He will not fail you or forsake you.”

And David said to Saul, “Let no man’s heart fail on account of him; your servant will go and fight with this Philistine.”

and he said, “Pay attention, all Judah and the inhabitants of Jerusalem and King Jehoshaphat: thus says Yahweh to you, ‘Do not fear or be dismayed because of this great multitude, for the battle is not yours but God’s.
