ערי מבצר וגדרת צאן FORTIFIED CITIES AND ENCLOSURES FOR SHEEP — This end of the verse is to be connected back with the beginning of the paragraph (v. 24): And the children of Gad built these cities to be fortified cities and enclosures for sheep.

To serve as fortified cities… Not that this was the reality, and the verse indicates that each of the cities mentioned were fortified and having pens for sheep, for if so, what is meant by “[the sons of Gad] built up” (v. 34) — surely they would had already been built.
