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. Alternate translation: "He also followed the example" (See: rc://en/ta/man/jit/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. Alternate translation: "the descendants of Ahab" (See: rc://en/ta/man/jit/figs-metonymy)
