Charles Ellicott Commentary Genesis 46:10

"And the sons of Simeon: Jemuel, and Jamin, and Ohad, and Jachin, and Zohar, and Shaul the son of a Canaanitish woman." — Genesis 46:10 (ASV)

Simeon has six sons:

Genesis 46:10: Jemuel, Jamin, Ohad, Jachin, Zohar, Shaul.

Numbers 26:12–13: Nemuel, Jamin, Jachin, Zerah, Shaul.

1 Chronicles 4:24: Nemuel, Jamin, Jarib, Zerah, Shaul.

Note: Ohad is omitted in the latter two lists. Jewish tradition holds that Shaul was the son of Dinah by Shechem, adopted by Simeon to preserve family honor.
