Although the wording is slightly different, the meaning of this verse is equivalent to verse 15, where the subject is “house” in place of “land.”

Add a fifth: see verse 13 and 5.16.

And it shall remain his: compare verse 15, where the same idea is expressed with the verb “to be” in place of the verb remain. This is the same difference noted at the end of verses 12 and 14.
