1 Chronicles 2:3

“There Judah met the daughter of a Canaanite man named Shua. He married her and slept with her; she conceived and gave birth to a son, who was named Er. She conceived again and gave birth to Onan. Then she gave birth to Shelah.”

This passage recounts the story of Judah's sons, Er, Onan, and Shelah, mentioned in 1 Chronicles 2:3.

“The sons of Judah were Er, Onan, Shelah, Perez and Zerah (but Er and Onan had died in the land of Canaan). The sons of Perez were Hezron and Hamul.”

Lists the sons of Judah who came to Egypt, mirroring the genealogy in 1 Chronicles 2:3 and noting the deaths of Er and Onan.

“These were the descendants of Judah by their clans: through Shelah, the Shelanite clan; through Perez, the Perezite clan; through Zerah, the Zerahite clan.”

Details the clans descended from Judah's sons, Perez and Zerah, as listed in 1 Chronicles 2:3.

“The descendants of Judah: Perez, Hezron, Carmi, Hur and Shobal.”

Continues the genealogical record of Judah's descendants, beginning with Perez as in 1 Chronicles 2:3.

“Through the offspring the Lord gives you by this young woman, may your family become like that of Perez, whom Tamar bore to Judah!"”

Refers back to the line of Perez, mentioned in 1 Chronicles 2:3, highlighting its significance in Israelite genealogy.
