Adam Clarke on Micah 1:16

Make thee bald - Cutting off the hair was a sign of great distress, and was practised on the death of near relatives; see Amo 8:10.

The desolation should be so great that Israel should feel it to her utmost extent; and the mourning should be like that of a mother for the death of her most delicate children.

Enlarge thy baldness as the eagle - Referring to the mounting of this bird, when in casting its feathers and breeding new ones, it is very sickly, and its strength wholly exhausted.

They are gone into captivity - This is a prediction of the captivity by Shalmaneser. Samaria, the chief city, is called on to deplore it, as then fast approaching.
