Final answer:
The period in question refers to the time when Joseph's legacy was seemingly forgotten in Egypt, which lasted for multiple generations until the liberation led by Moses. It spans an extensive period, ultimately described as 1,335 years, marking the interval from Joseph's prominence to a much later event in biblical history.
Step-by-step explanation:
The question seems to be referring to a period during which the biblical figure Joseph was forgotten. According to biblical chronology, around 1800 BCE, Joseph's family resettled in Egypt, marking the beginning of a lengthy sojourn. Joseph's descendants, over generations, were subjected to poor treatment and eventually enslaved under a Pharaoh in Egypt. This Pharaoh also ordered the killing of Hebrew male children. Interestingly, Moses was saved from this fate and raised by Egyptian royalty.
The duration of the Israelites' stay in Egypt was extensive and the period referenced in the question, 1,335 years, could relate to the overall time from Joseph's ascent to a period much later in biblical history. A narrative unrelated to Joseph's time in Egypt talks about a woman expecting marriage for fourteen years, which suggests a grasp of lingering expectations or forgotten deeds over time, akin to Joseph being forgotten by the cupbearer.
