Isaiah is a prophet making a prediction about horrible things that will or may happen in the future-----the lines that you quote are not DIRECTIVES or advocated actions. Try to grow a brain.
BULLSHIT! Notice the words "is" and "shall."
So how is this for a directive from the word of God:
1Sa 15:3
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.
that one is a directive -----Samuel. The stuff from Isaiah is not
There is no
word in Hebrew that translates into "is" or "shall"-----I have no idea why you
are PICKING words that some translator wrote
Shall

you made no point-----the words of Elijah are a PREDICTION---not a directive---
The words of Samuel are a directive that refer to the AMALEKITES only---
You are struggling to INTERPRET a translation which is only an approximation
of the original text In the Hebrew language----there are specific ways to express
an IMPERATIVE that differ from the expression of "future". I had an interesting
discussion with my son-------who insisted that there are jews in the world who would KILL an Amalekite if one showed up.. Amalekite is a non-extant nation.
Their claim to fame was the religious sacrifice of infants and the word is used
generically to describe an utterly evil and perverse people---with no chance of
recovery--------it does not describe any people today except in a curse-----some people called your hero Adolf "AMALEKITE" as a kind of curse
Your evil God did not limit his hate to just the Amalekites.
Num 31: 7 And they warred against the Midianites, as the LORD commanded Moses; and they slew all the males.
8 And they slew the kings of Midian, beside the rest of them that were slain; namely, Evi, and Rekem, and Zur, and Hur, and Reba, five kings of Midian: Balaam also the son of Beor they slew with the sword.
9 And the children of Israel took all the women of Midian captives, and their little ones, and took the spoil of all their cattle, and all their flocks, and all their goods.
10 And they burnt all their cities wherein they dwelt, and all their goodly castles, with fire.
11 And they took all the spoil, and all the prey, both of men and of beasts.
12 And they brought the captives, and the prey, and the spoil, unto Moses, and Eleazar the priest, and unto the congregation of the children of Israel, unto the camp at the plains of Moab, which are by Jordan near Jericho.
13 And Moses, and Eleazar the priest, and all the princes of the congregation, went forth to meet them without the camp.
14 And Moses was wroth with the officers of the host, with the captains over thousands, and captains over hundreds, which came from the battle.
15 And Moses said unto them, Have ye saved all the women alive?
16 Behold, these caused the children of Israel, through the counsel of Balaam, to commit trespass against the LORD in the matter of Peor, and there was a plague among the congregation of the LORD.
17 Now therefore kill every male among the little ones, and kill every woman that hath known man by lying with him.
18 But all the women children, that have not known a man by lying with him, keep alive for yourselves.
