Seth (Hebrew: שֵׁת, Standard Šet, Tiberian Šēṯ; Arabic: شيث‎ Shith or Shiyth; "Placed; appointed"), in Judaism, Christianity and Islam, he was the third son of Adam and Eve and brother of Cain and Abel, who were the only other of their children mentioned by name. According to Genesis 4:25, Seth was born after the slaying of Abel by Cain, and Eve believed God had appointed him as a replacement for Abel.

According to Genesis, Seth was born when Adam was 130 years old "a son in his likeness and image." The genealogy is repeated at 1 Chronicles 1:1-3. Genesis 5:4-5 states that Adam fathered "sons and daughters" before his death, aged 930 years. In Genesis 4:25, there is a folk etymology for Seth's name, which derives it from the Hebrew word for "plant" as in "plant a seed" (syt). Eve says, "God has planted another seed, under/replacing Abel's". Seth lived to the age of 912.

Rashi (Rabbi Shlomo Yitzhaqi) refers to Seth as the ancestor of Noah and hence the father of all mankind, all other humans having perished in the Great Flood.

Seth Bullock (July 23, 1849 – September 23, 1919) was a Western sheriff, hardware store owner and U.S. Marshal.

Many of the details of Bullock's early life are lost. He was born in Amherstburg, Canada West (now Ontario).

His father, retired British Army officer and hero George Bullock, was known to be active in the politics of Sandwich, Canada West (now known as Windsor, Ontario).^{[citation needed]} Seth's mother was a Scottish woman named Anna Findley Bullock. Apparently not happy at home, 16-year-old Bullock ran away to Montana to live temporarily with his older sister, Jessie Bullock. By age eighteen, he had permanently left home.

In 1867, Bullock became a resident of Helena, Montana, where he unsuccessfully ran for the Territorial Legislature. He was subsequently elected to the Territorial Senate, serving in 1871 and 1872 and helped create Yellowstone National Park. In 1873, he was elected sheriff of Lewis and Clark County, Montana. During his tenure as sheriff, he killed his first man, Clell Watson. Watson had stolen a horse and after a gunfight with Bullock, in which Bullock was slightly wounded in the shoulder, Watson was taken into custody. When Watson was prepared to be hanged, a lynch mob appeared and scared off the executioner. Bullock climbed the scaffold and pulled the lever, sending Watson to his death. Bullock then held off the mob with a shotgun. (This was recreated on HBO's Deadwood, except Watson was hanged on the step of the sheriff's office.)

The Black Hills (Pahá Sápa in Lakota, Moʼȯhta-voʼhonáaeva in Cheyenne) are a small, isolated mountain range rising from the Great Plains of North America in western South Dakota and extending into Wyoming, USA.Harney Peak, which rises to 7,244 feet (2,208 m), is the range's highest summit. The Black Hills encompass the Black Hills National Forest and are home to the tallest peaks of continental North America east of the Rockies. The name "Black Hills" is a translation of the Lakota Pahá Sápa. The hills were so-called because of their dark appearance from a distance, as they were covered in trees.

Native Americans have a long history in the Black Hills. After conquering the Cheyenne in 1776, the Lakota took over the territory of the Black Hills, which became central to their culture. In 1868, the U.S. government signed the Fort Laramie Treaty of 1868, exempting the Black Hills from all white settlement forever. However, when European Americans discovered gold there in 1874, as a result of George Armstrong Custer's Black Hills Expedition, erstwhile miners swept into the area in a gold rush. The US government re-assigned the Lakota, against their wishes, to other reservations in western South Dakota. Unlike most of South Dakota, the Black Hills were settled by European Americans primarily from population centers to the west and south of the region, as miners flocked there from earlier gold boom locations in Colorado and Montana.
