Deuteronomy 8:17

“Do not say in your heart when Yahweh your God has driven them out before you, saying, ‘Because of my righteousness Yahweh has brought me in to possess this land,’ but it is because of the wickedness of these nations that Yahweh is dispossessing them before you.

And Yahweh said to Gideon, “The people who are with you are too many for Me to give Midian into their hands, lest Israel honor themselves, saying, ‘My own hand has saved me.’

“Yahweh makes poor and rich; He brings low; He also exalts.

For by their own sword they did not possess the land, And their own arm did not save them, But Your right hand and Your arm and the light of Your presence, For You favored them.

I again saw under the sun that the race is not to the swift and the battle is not to the mighty, and neither is bread to the wise nor riches to the discerning nor favor to men who know; for time and misfortune overtake them all.
