<span>The threat to internal validity is the Mortality. Internal
validity is the measure in which the causality of the stimuli studied
is analyzed, that is, if the results of the study are due to the
interaction of the variables analyzed or are due to the interaction with
other variables. <span>Mortality is an error that occurs if the
conclusions of the study are made only on the basis of the participants
who were from beginning to end in the investigation, without taking into
account those who left the study.

Abraham Joshua Heschel asserts that the Sabbath is a sanctuary that we create. It is a haven in time.
A sanctuary is a holy location, like a shrine, according to the word's original definition. The phrase has evolved to refer to any location of safety as a result of the utilization of places like havens. This second application can be divided into two categories: human sanctuary, a location where sanctuary individuals can feel safe, like a political refuge; and non-human sanctuary, such an animal or plant sanctuary.
Because of what occurred there, it was believed that the location and the church that was built there had been sanctified (made holy). A casket (the sepulcrum) containing the relics of one or more saints, typically political refuge martyrs, is placed on the altar of each church when it is consecrated for use in sanctuary modern times as a continuation of this tradition by the Catholic Church. When the church is no longer used as a sacred sanctuary, this relic box is taken down. The antimension on the altar performs a similar purpose in the Eastern Orthodox Church. A saint's relics are frequently embroidered onto this cloth icon portraying Christ's body being removed from the cross.
