For you have not come to what may be touched, a blazing fire and darkness and gloom and a tempest and the sound of a trumpet and a voice whose words made the hearers beg that no further messages be spoken to them. For they could not endure the order that was given,"If even a beast touches the mountain, it shall be stoned." Indeed, so terrifying was the sight that Moses said, "I tremble with fear." But you have come to Mount Zion and to the city of the living God, the heavenly Jerusalem, and to innumerable angels in festal gathering, and to the assembly of the firstborn who are enrolled in heaven, and to God, the judge of all, and to the spirits of the righteous made perfect, and to Jesus, the mediator of a new covenant, and to the sprinkled blood that speaks a better word than the blood of Abel.

hebrews 12:18-24

The sons born to Hezron were: Jerahmeel, Ram and Caleb. Ram was the father of Amminadab, and Amminadab the father of Nahshon, the leader of the people of Judah. Nahshon was the father of Salmon, Salmon the father of Boaz...

according to the legends of the rabbis, Nahshon was beside Moses as he led the people of Israel out of Egypt. when they arrived at the red sea, the armies of pharaoh were close behind. the fiery tornado came down from heaven, keeping pharaoh's men back from the people, and Nahshon asked Moses where the people were to go. Moses told the people to watch for the salvation of Yahweh. Nahshon looked down from the cliff they stood on into the raging red sea below them. he turned to Moses and asked, "Yahweh will open the sea for us?" Moses nodded his head and raised his staff over the sea, and immediately Nahshon jumped off the cliff. he landed in shallow water and walked further into the sea, until at last only his head remained out of the water, but still he walked. when his nostrils went under water, the wind came down from Yahweh and split the sea in two before him.

this, they say, is why Nahshon is the first elder to bring an offering to Yahweh, and how he received his name, which means "stormy sea-waves." Nahshon's descendants include David, Solomon, Daniel, Hananiah, Mishael, Azariah (though we know them as Shadrach, Meshach, and Abednego), and Jesus Christ.
