Leviticus 26:8

Only rebel not ye against the LORD, neither fear ye the people of the land; for they are bread for us: their defense is departed from them, and the LORD is with us: fear them not.

The LORD shall cause thine enemies that rise up against thee to be smitten before thy face: they shall come out against thee one way, and flee before thee seven ways.

How should one chase a thousand, and two put ten thousand to flight, except their Rock had sold them, and the LORD had shut them up?

One man of you shall chase a thousand: for the LORD your God, he it is that fighteth for you, as he hath promised you.

And Jonathan said to the young man that bare his armor, Come, and let us go over unto the garrison of these uncircumcised: it may be that the LORD will work for us: for there is no restraint to the LORD to save by many or by few. And his armourbearer said unto him, Do all that is in thine heart: turn thee; behold, I am with thee according to thy heart. Then said Jonathan, Behold, we will pass over unto these men, and we will discover ourselves unto them. If they say thus unto us, Tarry until we come to you; then we will stand still in our place, and will not go up unto them. But if they say thus, Come up unto us; then we will go up: for the LORD hath delivered them into our hand: and this shall be a sign unto us. And both of them discovered themselves unto the garrison of the Philistines: and the Philistines said, Behold, the Hebrews come forth out of the holes where they had hid themselves. And the men of the garrison answered Jonathan and his armourbearer, and said, Come up to us, and we will show you a thing. And Jonathan said unto his armourbearer, Come up after me: for the LORD hath delivered them into the hand of Israel. And Jonathan climbed up upon his hands and upon his feet, and his armourbearer after him: and they fell before Jonathan; and his armourbearer slew after him. And that first slaughter, which Jonathan and his armourbearer made, was about twenty men, within as it were an half acre of land, which a yoke of oxen might plow. And there was trembling in the host, in the field, and among all the people: the garrison, and the spoilers, they also trembled, and the earth quaked: so it was a very great trembling. And the watchmen of Saul in Gibeah of Benjamin looked; and, behold, the multitude melted away, and they went on beating down one another.
