You clearly have never read the entire book like I did (carefully, when I was a biblicist).
I don't hate anybody - but congratulations, that means you just violated the commandment against false witness, which is basically no different than you committing adultery.
Now for the citation. I'll give you just one, because you need to get off your lazy @$$ and go read the thing yourself.

“Now go and smite Amalek, and utterly destroy all that they have, and spare them not; but slay both man and woman, infant and suckling, ox and sheep, camel and ass.”
For the historiography, again, get your illiterate butt in gear and learn to use the internet. This is only one example, that simply tells you where history has moved to in questioning the texts when they do not square with the archeology and facts:
https://en.wikipedia.org/wiki/The_Exodus
"The Exodus (Hebrew: יציאת מצרים, Yeẓi’at Miẓrayim: lit. 'Departure from Egypt') is the founding myth of the Israelites.[1][a] It tells of their departure from Egypt, the revelations at biblical Mount Sinai, and their wanderings in the wilderness up to the borders of Canaan.[2] Its message is that the Israelites were delivered from slavery by Yahweh their god, and therefore belong to him by covenant.[1]
The consensus of modern scholars is that the Bible does not give an accurate account of the origins of the Israelites, who appear instead to have formed as an entity in the central highlands of Canaan in the late second millennium BCE from the indigenous Canaanite culture.[3][4][5] Most modern scholars believe that the story of the Exodus has some historical core,[6] but the Bible was never intended primarily as a historical document, and contains little that is accurate or reliable.[7]
You want to believe, go ahead. But don't whitewash over the fact IN THE BIBLE TEXT ITSELF of the Canaanite genocide.
I seriously can't believe you claim to be Christian and not know this.
Oh wait, most Christians are bible-illiterate, so actually yes I can.
End of discussion. Go fix your vast ignorance yourself.
