A burnt offering in Judaism is a form of sacrifice first described in the Hebrew Bible.

The Hebrew noun olah (עֹלָה) occurs 289 times in the Masoretic Text of the Hebrew Bible. It means "that which goes up [in flames]". Its traditional name in English is "holocaust", and the word olah has traditionally been translated as "burnt offering."

The first uses of olah for burnt offering are the animal sacrifices of Noah (Genesis 8:20) and the near-sacrifice of Isaac by Abraham: "Sacrifice him there as a burnt offering on a mountain I will show you" (Genesis 22:2).

From the Hebrew Bible, Isaiah 40:

Before YHWH all the goyim are as nothing; they are regarded by YHWH as worthless and less than nothing.

From the Jewish Torah, Deuteronomy 13:

If you hear it said about one of the towns YHWH is giving you to live in that troublemakers have arisen among you and have led the people of their town astray, saying, “Let us go and worship other gods” (gods you have not known), then you must inquire, probe and investigate it thoroughly. And if it is true and it has been proved that this detestable thing has been done among you, you must certainly put to the sword all who live in that town. You must destroy it completely, both its people and its livestock. You are to gather all the plunder of the town into the middle of the public square and completely burn the town and all its plunder as a whole burnt offering to YHWH. That town is to remain a ruin forever, never to be rebuilt, and none of the condemned things are to be found in your hands. Then YHWH will turn from his fierce anger, will show you mercy, and will have compassion on you. He will increase your numbers, as he promised on oath to your ancestors — because you obey YHWH by keeping all his commands that I am giving you today and doing what is right in his eyes.

From the Jewish Torah, Deuteronomy 20:
https://biblehub.com/niv/deuteronomy/20.htm

When you march up to attack a city, make its people an offer of peace. If they accept and open their gates, all the people in it shall be subject to forced labor and shall work for you. If they refuse to make peace and they engage you in battle, lay siege to that city. When YHWH delivers it into your hand, put to the sword all the men in it. As for the women, the children, the livestock and everything else in the city, you may take these as plunder for yourselves. And you may use the plunder YHWH gives you from your enemies. This is how you are to treat all the cities that are at a distance from you and do not belong to the goyim nearby.

However, in the cities of the goyim YHWH gives over to you, do not leave alive anything that breathes.

From the Jewish Torah, Deuteronomy 7:
https://biblehub.com/niv/deuteronomy/7.htm

You must destroy all the goyim YHWH gives over to you. Do not look on them with pity and do not serve their gods, for that will be a snare to you.

YHWH will drive out those goyim before you, little by little. You will not be allowed to eliminate them all at once, or the wild animals will multiply around you. But YHWH will deliver them over to you, throwing them into great confusion until they are destroyed. He will give their kings into your hand, and you will wipe out their names from under heaven. No one will be able to stand up against you; you will destroy them.
