when is moses first mentioned in the bible
Moses According to the Book of Exodus, Moses was born in a time when his people, the Israelites, an enslaved minority, were increasing in numbers and the Egyptian Pharaoh was worried that they might ally themselves with Egypt's enemies.[5] Moses' Hebrew mother, Jochebed, secretly hid him when the Pharaoh ordered all newborn Hebrew boys to be killed in order to reduce the population of the Israelites. Through the Pharaoh's daughter (identified as Queen Bithia in the Midrash), the child was adopted as a foundling from the Nile river and grew up with the Egyptian royal family. After killing an Egyptian slavemaster (because the slavemaster was smiting a Hebrew), Moses fled across the Red Sea to Midian, where he encountered The Angel of the Lord,[6] speaking to him from within a burning bush on Mount Horeb (which he regarded as the Mountain of God).
Ark of the Covenant According to the Book of Exodus, God instructed Moses on Mount Sinai during his 40-day stay upon the mountain within the thick cloud and darkness where God was[4][5] and he was shown the pattern for the tabernacle and furnishings of the Ark to be made of shittim wood to house the Tablets of Stone. Moses instructed Bezalel and Oholiab to construct the Ark.[6][7] In Deuteronomy, however, the Ark is said to have been built specifically by Moses himself without reference of Bezalel or Oholiab.[8]
