Leviticus 20:26

“Indeed, how then can it be known that I have found favor in Your sight, I and Your people? Is it not by Your going with us, so that we, I and Your people, may be distinguished from all the other people who are upon the face of the earth?”

“Speak to all the congregation of the sons of Israel and say to them, ‘You shall be holy, for I, Yahweh your God, am holy.

‘Hence I have said to you, “You yourselves shall possess their land, and I Myself will give it to you to possess it, a land flowing with milk and honey.” I am Yahweh your God, who has separated you from the peoples.

“For you are a holy people to Yahweh your God, and Yahweh has chosen you to be a people for His treasured possession out of all the peoples who are on the face of the earth.

Then Joshua said to the people, “You will not be able to serve Yahweh, for He is a holy God. He is a jealous God; He will not forgive your transgression or your sins.
