Jesus did not build an army.
(Disclaimer: I am too lazy to find a part of the Bible in which it states this.)
The term of office for a United States senator is 6 years.
Each senator's mandate lasts for 6 years, and usually, new senators are chosen every two years as the old senators' mandate finishes. In the US, each state is allowed to have 2 senators in the Congress, for a total of 100 senators.
In 1793, Eli Whitney invented a simple machine that influenced the history of the United States. He invented a cotton gin that was popular in the South. The South became the cotton producing part of the country because Whitney's cotton gin was able to successfully pull out the seeds from the cotton bolls.
