In what campaign did god extend the day this allowed Israel to rout the enemy

Answers

Answer: Against the five Amorite Kings

Explanation:

As the Israelites journeyed from Egypt to Canaan, they had to fight a number of nations who had come out to destroy them so that they would not reach Canaan. Gideon was no such nation. Gideon decided to make peace with Israel so that they would not suffer defeat.

When the other Amorite Kings including the kings of Jerusalem, Hebron, Jarmuth, Lachish and Eglon heard of it they went to attack Gideon which sent messages to Joshua(leader of Israel) asking for help.

Joshua arrived to save his allies and defeated the Amorites but because night was coming and the Amorites would escape under cover of darkness, Joshua ordered the sun to remain where it was and give Israel another day so that they could completely defeat the Amorites. God granted this and Israel was able to rout the enemy.

Two to three sentences describing how Native Americans contributed to the war effort and how these contributions impacted the outcome of the Revolutionary War

Answers

Answer:

The first few Native Americans to join the war chose to help the the patriots. Some other Native Americans joined the British side and fought to defeat the American invasion of Canada. The British had an advantage when convincing the Native Americans to join them: While the colonists were eager to spread westward and discover other places, the British policies before the war had tried to limit the encroachment of white settlers onto Native lands.

If you need more help on the subject, I suggest looking through this: https://www.battlefields.org/learn/articles/roles-native-americans-during-revolution

During the American Revolutionary War, Native Americans took different sides. They contributed to the war as:

Spies informing the Americans of British plans Soldiers fighting against the British and the Americans

Some Native Americans such as the Maliseet allied themselves with the Americans and usually went to Canada where they could spy on the British. They would then relay what they saw to the colonists.

Other Native Americans engaged in battle such as the Oneida who fought alongside the colonists at Saratoga.

The actions of the Oneida impacted the Revolutionary War because their support of the Americans allowed the colonists to hold onto New York and avoid defeat at the hands of the British.

In conclusion, the Native Americans were quite involved in the American Revolutionary War by helping both sides.

Should citizens arrests be allowed? why?

Answers

Answer:

This depends....see explanation  below:

Explanation:

This could go one of two ways, if allowed.

A) People would go crazy arresting people for minor offenses or absolute nonsense, and police stations would be filled with people in handcuffs for going 6 over the speed limit. And when people are given power, it makes them think that they're now able to use force in unneccesary situations. We'd have chaos in the streets.

B) Cops don't always do their job, and there are good people out there who can help. If some creep is disturbing a young woman on the sidewalk at night and takes it way too far, a good samaritan could come by and arrest him, taking care of the problem right then and there.

It really does depend on the situation, which is why it may not be a good idea.

Could we really trust everyone to use this for good?
