for the band of men ... had killed all his older sons

This is background information about the events of 2 Chronicles 21:16-17. Ahaziah was called "Jehoahaz" in that earlier account. It is possible he changed his name when he became king. (See: rc://en/ta/man/translate/writing-background)

all his older sons

"all Jehoram's older sons"

twenty-two years old

"22 years old" (See: rc://en/ta/man/translate/translate-numbers)

Athaliah

This is the name of Ahaziah's mother. (See: rc://en/ta/man/translate/translate-names)

He also walked in the ways

Here "walked in the ways" is an idiom that means he followed Ahab's example. See how you translated this in 2 Chronicles 20:32. AT: "He also followed the example" (See: rc://en/ta/man/translate/figs-idiom)

the house of Ahab

The word "house" is a metonym for the family that lives in the house. In this case it refers to the descendants of Ahab. See how you translated this in 2 Chronicles 21:6. AT: "the descendants of Ahab" (See: rc://en/ta/man/translate/figs-metonymy)
