Adam Clarke on Nehemiah 4:16

Half - wrought in the work - This is no unusual thing, even in the present day, in Palestine: people sowing their seed are often attended by an armed man, to prevent the Arabs from robbing them of their seed, which they will not fail to do if not protected.

Habergeons - In the Franco-Gallic, hautbergon signifies a coat of mail; but as in Teutonic hais signifies the neck, and bergen, to cover or defend; it may be considered rather as signifying a breastplate, or armor for the breast.
