The Haftarah of Balak is from Micha, a contemporary of Yeshayahu, with an equally poetic style.
Linear annotated translation of the Haftarah of Balak
This Haftarah ends with a very well-known verse, which contains one of only two times the root “צנע”, “modesty”, appears in all of Tanach.
Connections to Parshat Balak include the image of the Jewish People as a lion, the special relationship G-d has with us vs the Nations of the World, and: G-d does not work for us – what Bilaam thought he was doing.
